Mac OS X Snow Leopard is a resilient operating system, but it isn't impenetrable. There are some things you should do to protect your Mac from bad things, like OS instability. Here’s a list of Mac do's and don'ts:

* Don't unplug your Mac when it's turned on: Very bad things can happen, such as having your operating system break.
* Don't use your Mac when lightning is near: Here's a simple life equation for you: Mac + lightning = dead Mac. Oh, and don't place much faith in inexpensive surge protectors. A good jolt of lightning will fry the surge protector right along with your computer as well as possibly frying your modem, printer, and anything else plugged into it. Some surge protectors can withstand most lightning strikes, but those warriors aren't the cheapies that you buy at your local computer emporium. Unplugging your Mac from the wall during electrical storms is safer and less expensive. (Don't forget to unplug your external modem, network hubs, printers, and other hardware that plugs into the wall, as well; lightning can fry them, too.)
* Don't jostle, bump, shake, kick, throw, dribble, or punt your Mac, especially while it's running. Your Mac contains a hard drive that spins at 4,200 revolutions per minute (rpm) or more. A jolt to a hard drive while it's reading or writing a file can cause the head to crash into the disk, which can render many — or all — files on it unrecoverable. Ouch!
* Don't forget to back up your data: If the stuff on your hard drive means anything to you, you must back it up. Not maybe, must. Even if your most important file is your last saved game of Call of Duty 2, you still need to realize how important it is to back up your files. Fortunately, Mac OS X Snow Leopard includes an awesome backup utility called Time Machine. (Unfortunately, you need either an external hard drive or an Apple Time Capsule device to take advantage of it.)
* Don't kiss your monitor while wearing stuff on your lips: For obvious reasons! Use a soft cloth and/or OmniCleanz display cleaning solution to clean your display.

A lot has happened during the past 18 years. The Cold War ended, mobile phones appeared, Diff'rent Strokes went off the air and Lara Croft became a sex symbol. Yet during this time the battle over which are better, PCs or Macs, continued to rage.

This hasn't been a mere argument, either. People from both camps became evangelical, created countless newsgroups and websites advocating their views - Mac Sucks is a typical one - and when Steve Jobs announced Microsoft would invest in Apple at 1997's MacWorld Expo, the crowd booed, hissed and some even turned their back on him.

For some people, computers aren't a tool - they're a religion.

Well, Icon has had enough from both sides. We've decided it's time to take a stand and pick a winner - and for those who will inevitably disagree with our conclusion, remember: violence is not the solution.

To critique both platforms we have used the following criteria: ease-of-use, software, performance, stability, style and design, and last, cost. We have awarded points out of 10 for each category and totalled them to find the winner.

Because we have compared the platforms from a home user's perspective, we looked at the OS X (10.2) operating system for Apples and Windows XP Home Edition for PCs. We used a variety of computers for this feature but primarily focused on the 15- and 17-inch G4 iMacs and the Acer T300 desktop PC because we deemed them to be average, mid-range systems.

Ease-of-use

Macs have always been known for their ease of use but they've certainly lost their lead.

"Today the two interfaces are so close it's a toss-up what's easiest," says Dr Jakob Neilsen, one of the world's leading usability experts. "The PC has made huge progress from a crummy, substandard design that only a nerd could love to a decent user interface. In contrast, the Mac has made very little progress from a decent and restrained user interface to a decent and flashy user interface."

We'd have to agree. OS X initially seems easier to use, especially with its large "Dock" at the bottom of the screen that clearly shows some of the major applications available, but OS X can also be frustrating. For example, there's no specific place where you can always, without fail, find a specific application to load. It could be in the Dock, or in the Applications folder, or on the Desktop, whereas all Windows applications can be found from the Start menu, in addition to being found elsewhere.

Neilsen says Windows XP has another advantage, provided you have a flat-panel display: its ClearType technology that displays text more crisply.

"It takes advantage of the fact that each 'pixel' on a flat panel is actually three smaller pixels for red, green and blue, and ClearType manages each of these sub-pixels separately. The effect is stunning and almost approximates the clarity of printed text," Neilson says. "Users can read text about 10 per cent faster after turning ClearType on. Since the two platforms are so similar, ClearType makes the difference to me."

However, ClearType has to be activated manually (it's buried deep within Control Panel/Appearance and Themes/Display/Appearance/Effects) and most PC users aren't aware it even exists - and without it we found the Mac easier to read.

Also, as Neilsen says, many Mac applications such as iPhoto are easier to use than their PC equivalents. As such, we have to call it a draw.

PC: 7/10 Apple: 7/10

Software

PCs certainly have more software than the Mac but what's important is whether the particular titles you want are available - and the Mac has most application areas well covered. With office software, for example, the Mac not only has a version of Microsoft Office called MacOffice but also AppleWorks, an office-like suite that comes free on iMacs. Internet applications such as web browsers, instant messaging and email are plentiful, as are utilities such as anti-virus packages.

An area in which Macs once excelled is graphics and video editing but PCs have largely caught up. In fact, Adobe recently decided to release the latest version of its Premiere video-editing software only on the PC.

However, games are a different matter. The Mac has a number of titles but it's nowhere near as well catered for as the PC. More niche areas, such as voice recognition, are limited on the Mac. The voice-recognition package Dragon NaturallySpeaking, for example, is available only on the PC.

As such, the PC wins when it comes to software availability.

PC: 9/10 Apple: 7/10

Performance

The question of which platform is the fastest has always been contentious. Last year, for example, Adobe claimed PCs were faster than Macs by running After Effects, Illustrator and Photoshop operations on both a single-processor Dell 2.53GHz Pentium 4 and a 1.25GHz dual-processor Power Mac G4. Apple, however, argued that the problem was with those particular applications and that some tasks could perform faster on a Mac with different software.

This year Apple claimed its new Power Mac G5 (which uses a 64-bit processor codeveloped with IBM) was the world's fastest personal computer and outperformed 3GHz Dell machines using Pentium 4 and Xeon processors. Within hours, criticism surfaced that the benchmarks and testing procedure were slated against PCs.

For average home users, however, these arguments are largely academic because most don't make the most of the processor speed they already have.

"At the end of the day, applications are not catching up as fast as the hardware," says Andy Woo, a hardware analyst at Gartner. "Hardware, speed and power are not as critical anymore."

To play the devil's advocate, we ran a number of matching applications on both platforms, including Macromedia's Dreamweaver and Fireworks, Warcraft III, Microsoft Office, Harry Potter and the Chamber of Secrets and, for the most part, we couldn't tell the difference. That's not to say there wasn't any. The animation and graphic detail in the PC version of Harry Potter were slightly better while an operation in Fireworks (rotating a 472KB JPEG image) was noticeably faster on our test PCs. We ran the latter test on a Pentium 4 2.66GHz Acer T300 with 512MB RAM, a Pentium 4 1.7GHz Dell Dimension with 384MB RAM, a 1.8GHz Pentium 4-M BenQ laptop with 256MB RAM, and a 1GHz G4 iMac with 256MB RAM. The iMac was the slowest, taking 6.4 seconds, while the Dell, our slowest PC, took 2.4 seconds.

It should also be noted that even some Mac users acknowledge that the G4 processors are lagging behind Intel's. The Mac-oriented site Bare Feats, for example, has benchmarked both and shows the Pentium 4 is faster.

Since it's also easier to boost a PC's speed by upgrading the graphics card or processor, we've made it the winner in this category.

PC: 9/10 Apple: 8/10

Stability

Both XP and OS X crash less than previous versions but it's the latter that has the better reputation because it is based on the stable UNIX operating system. Most studies find this.

In PC Magazine's 2003 Service and Reliability Survey, for example, Mac OS X crashed less for users than Windows XP (as well as other Windows versions), while ConsumerReports.org's 2003 survey showed that Apples crashed less than PCs from other companies (although Dell came a close second). A survey last year by the Australian Consumers Association (ACA) had similar results. "Apple stood out for reliability with 86 per cent of owners reporting no repairs in the past 12 months," says Jessica Ross, editor of Computer Choice, an ACA publication, "but, mind you, Dell came in at 83 per cent and IBM at 82."

Macs are also more secure than PCs because most viruses are created for PCs. "Whereas there are tens of thousands of viruses for the PC platform, there are only hundreds of viruses for the Mac," says Paul Ducklin, head of technology at the anti-virus firm Sophos. However, Ducklin says virus writers may target Macs more as they increase in popularity, and that macro viruses, which work through Microsoft Office, work on both platforms.

We acknowledge Macs aren't perfect - one of our test iMacs crashed on the second day - but Apple still wins this category.

PC: 6/10 Apple: 9/10

Style and design

Beauty may be in the eye of the beholder but there's no doubt more attention was put into the iMac's design than into any desktop PC.

First, the iMac is extremely compact - the main unit is encased in a small base that also supports the flat screen via a chrome arm that allows you to raise, tilt and rotate the screen more easily than any monitor we've seen. The arm is also strong enough to act as a handle.

Apple also intended the iMac to be thought of more as an appliance than a computer. Its all-in-one design makes it easier to set up and instead of looking like a box with slots and protruding buttons, the dome-shaped base has a smooth front with the optical drive merely an outline. Until you press the keyboard's eject button you almost wouldn't notice it.

Last - and, admittedly, this is subjective - we believe the iMac looks more elegant than any desktop PC we've seen.

PC: 4/10 Apple: 9/10

Cost

Macs have a reputation for being expensive but this isn't necessarily so. For operating systems alone they're actually cheaper - OS X 10.2 costs $229 while Windows XP Home is $463. Comparing the cost of full desktop systems is harder, but if you're buying a brand-name PC you probably won't pay less. For example, the new 15-inch iMac (which was just announced at the time of writing) is $2299 while an Acer T300 with a 15-in LCD monitor and similar specs (that is, 256MB RAM and an 80GB hard-drive) is $2420.

There are, however, exceptions. For example, you can buy a Dell Dimension with roughly the same specs for several hundred dollars less (this is because Dell sells directly to consumers rather than through retail outlets).

Another option is to buy a "no-name" PC from a local store, although the support and overall quality is sometimes not as good.

As such, the PC won this category, albeit by a small margin.

PC: 9/10 Apple: 8/10

And the winner is ...

The Mac - but not by much. We've given it a score of 48 out of 60, while the PC received 45.

The Mac won primarily because of its design and if it had kept its lead in usability, the margin would have been greater. Also, its performance suffered slightly but this is likely to be remedied by the new G5 processors. However, we do believe PCs are better suited for games and running specific software titles.

For many years you have paid a premium for lightness and portability in a laptop, the less they hurt your shoulder the more they were going to damage your wallet.

However recently thanks to improved technology allowing processors to run faster but not overheat, small no longer always equate to expensive. Admittedly the first 3 laptops reviewed : the Toshiba Protege R500, Sony VAIO TZ150 and Apple MacBook Air are all going to cost you over US$2000 mark. However the Averatec is priced well under US$1500 and the innovative Asus Eee PC will set you back less than US$500! So now is an exciting time to be buying a truly ultraportable laptop!

Toshiba Protege R500

This laptop manages to fit a full sized keyboard with a 12.1-inch screen and a native resolution of 1,280x800 and that's a matt screen too. This well-known brand doesn't come cheap but Toshiba's reputation is well deserved for reliable, well-engineered laptops.

Price point: an expensive laptop where you are paying for the convenience and lightness. Main Competitors: Sony VAIO, Fujistsu Lifebooks

Aimed at: the corporate/business market which requires a big name brand, excellent support and backup and can afford to pay for it.
The Good:
* 12-inch display but lighter than some 11-inch notebooks.
* Avoids the annoying ultraportable trick of eliminating important keys, squeezing in separate page-up and page-down keys
* Better performance than the Sony VAIO
* A fingerprint reader
* Excellent battery life of 5 hours under standard conditions.
* Standard 3 year mail-in warranty.

The Bad:
* Lack of mobile broadband antenna EV-DO
* Only a SD card slot not a multifunction card reader
* No WebCam
* Only quicklaunch buttons are brightness mode and a button for launching Toshiba's proprietary help utility.

A beautiful design which gives even the style icons at Apple a run for their money. Just manages to beat the Toshiba R500 on battery life and size. The 11.1-inch laptop combines an ultrathin, LED-backlit display and even with an optical drive, this system is amazingly only about an inch thick. However the Toshiba does weigh slightly less. With a native resolution of 1,366x768 the text is small and hard to see, but that's the trade-off for such a small screen. The screen is matt which is a nice change for the currently popular shiny screens.

Like the Toshiba R500 the Sony is aimed for: the corporate/business market which requires a big name brand, excellent support and backup and can afford to pay for it.

Adding a solid state drive will push the price over $3000. Unless you are prepared to pay for a lot for the design aesthetic the Toshiba is probably a better deal.

Sony's standard one-year warranty can be extended a number of ways at extra cost to include up to 4 years on-site and accidental damage protection
The good:
* Extremely slim and light with a stunning good looks.
* Almost impossibly slim, the body of the Sony VAIO TZ measures just less than an inch thick. Adding the standard battery raises the rear of the laptop slightly, to 1.17 inches thick, but this is still one of the smallest laptops you're find.
* Fantastic battery life at over 5 hours.
* Includes integrated WWAN with EV-DO for web surfing via hot-spots.
* Includes an integrated DVD burner.
* Includes an integrated Webcam.
* Includes a Firewire port.

The bad:
* Slow performance the slower processor 1GB memory and slower disk are not helped by the bloat ware which clutters the hard drive
* Only 2 USB ports.

MacBook Air

Although not the as light as the Toshiba R500 the Air it still easily breaks new ground for small laptops.

Mimicking the 13-inch silhouette of the current MacBook line, it's only 0.76 inch thick at its thickest part, and Apple calls it the "world's thinnest notebook".

The MacBook Air is certainly a sexy, stylish, thin laptop. It does however come at a substantial price and costs significantly more than the MacBook Pro's which offer more connectivity and speed for less money, though with more weight.

The innovative touch pad gesture controls will win some fans as will the ability to wirelessly "borrow" optical drives attached to nearby desktops. Alterntaively you can purchase the USB-powered superdrive at an additional US$99.

While the MacBook Air's configuration is inferior to those found on the cheaper MacBook, they compare more favorably when you look at other ultraportables. . Both the Toshiba Portege R500 and Sony VAIO TZ150 cost hundreds more than the MacBook Air and feature slower CPUs and half the RAM as the Air.

One thing to be aware of though is that the custom battery is not replaceable by the user, which means if you want longer than the approximately 5 hours of battery life carrying a spare is not an option.

The MacBook Air is covered by a standard 1 year parts and labor warranty.
The Good Points
* Includes integrated webcam and mike,
* LED backlit display that responds to room brightness.
* Full size backlite keyboard

The Bad Points:
* Lack of connectivity is the biggest negative - only 1 USB no firewire FireWire, Ethernet, or mobile broadband
* No media card reader
* No optical drive

Averatec 1579

A good value for money option for those who don't want to spend the top dollars for the Sony Vaio or Toshiba Protege models. Although costs approximately 25% less than the premium machines the Averatec supplies a robust 11.1-inch ultraportable with good performance, great battery life and solid construction.

At 1.5-inches the Averatec is noticeably thicker than other laptops reviewed but still manages to weight in at 3.4 pounds - just proving yet again than the less weight the more dollars it's going to cost!

The 11.1-inch wide-screen display features a 1,366x768 native resolution, which offers a decent balance of screen real estate and readability

Averatec includes an industry-standard one-year parts-and-labor warranty with the system.
The Good:

* Reasonable performance in a tidy package at an competitive price.
* DVD burner included
* Mini FireWire jack and an ExpressCard slot included

The Bad:

* Somewhat cramped keyboard.
* No media control button
* No webcam

Asus Eee PC

Starting from under US$200 there has been a sudden rush to the market of these tiny laptops may look and sound like a toy but they aren't. Netbooks are a new option for many people who want to save money and wonder if they should buy a netbook

Instead they are realistic entry point for those who until now couldn't afford a PC, never mind a laptop. Or a child or student who needs a small portable model they can carry everyday without fearing it being stolen or a bad back from the weight. Or a backpacker who wants something light and robust to travel with.

In particular the price includes bundled software for web browsing, FireFox, and office productivity, OpenOffice, so there is absolutely no need to spend more money getting up and running with basic word-processing, spread-sheeting, presentation and web applications. Also included are a generic media player, an instant messaging client that works with popular IM systems, and some preinstalled games.

However the operating system is Linux not Windows so some software won't run at all such as such as iTunes or Photoshop.

The Eee PC has a just 7" screen which obviously means some compromises on keyboard size, particularly for the non-letter keys, but at 2 pounds its great to carry around. The Eee PC's competitors may well be pocket PC's and mobile phones with keyboards, and compared to these the Eee PC's keyboard is a whole lot more functional.

Asus offers a 1 year parts and labor warranty.
The good:
* Small, light, and inexpensive;
* Solid-state hard drive is fast and efficient;
* Well-thought-out preinstalled software package.
* 3USB ports, a VGA out, and standard headphone and mic jacks
* SD card slot. allows you to expand the hard-drive capacity.
* 3.5 hour battery life.

The bad:
* Cramped keyboard;
* Little hard drive space;
* Low screen resolution.
* No optical drive or firewire port

Reff:http://hubpages.com/hub/Light-Notebooks---Review-of-5-Lightest-Laptops-

Macworld - It’s spring again, and with the new season comes the age-old ritual of cleaning out things you ignored for most of the year. Far be it from me to suggest that you clean out your basement, garage, or attic, but I would be remiss if I didn’t recommend you take a closer look at the crusty corners of your Mac. Last year, Chris Breen shared valuable Tips for a tidier Mac—all of which are worth revisiting. But I also want to draw your attention to a half-dozen digital dust bunnies that you might not have considered:
1. Get rid of old iChat logs

If you use iChat, you can have the program store logs of your chats. (Go to iChat -> Preferences, click on Messages, select Save Chat Transcripts To, and then choose a folder.) By default, the program saves transcripts in a folder called iChats in your Documents folder, but you can choose a different location to store these files.

With this preference set, iChat saves a log file of every chat. This is a great idea (and especially helpful at work) if you often need to refresh your memory about a conversation. But if you send images inline during chats, these files may take up a lot of space. If you look inside the iChats folder, you’ll see that the files are organized by date. While you may want to save recent chat logs, you may have months of files you can trash, saving a lot of disk space.
2. Delete application backups

Many programs offer automatic backups, and store copies of files in a selected folder, just as iChat saves chat logs. Two programs I use often—Bare Bones Software’s BBEdit and The Omni Group’s OmniFocus—do this. Some applications, such as OmniFocus, let you choose the location for the backups; others, like BBEdit, don’t. BBEdit stores its backups in a BBEdit Backups folder in my Documents folder; I have OmniFocus store its backups in my Documents folder as well.

If you use any application that saves backups, you may find that it has tucked away several gigabytes of duplicate files, depending on how the program saves them. (BBEdit saves a new backup every time you save a file.) Deleting these backup files can save space, and make searching via OS X’s Spotlight much easier.

While you’re at it, check in youruserfolder/Music/iTunes folder; you may find a Previous Libraries folder, which includes copies of your iTunes libraries that were saved after you installed a new version.
3. Get rid of Mail downloads

When you receive attachments to e-mail messages in Apple’s Mail, the files are stored with your messages at first. But if you double-click an attachment to view it, or if you use QuickLook to glance at it, Mail stores a copy in your youruserfolder/Library/Mail Downloads folder. You may have dozens of files here occupying a huge amount of space. You can generally delete these without worry. If you still have the original messages, the attachments are part of those messages. If not, you may have already saved the attachments to your hard disk.

4. Delete log files

Your Mac stores lots of log files, most of which you never need to review. Open the Console application (in /Applications/Utilities), to see a list in the Console Messages window sidebar.

You can delete many of these files without affecting your Mac, and you can save significant space, since some of these files can be quite large. For instance, in the screenshot above, you can see a number of system.log files. The first one—system.log—is the current file, but the others, with the .bz2 suffix, are archived files.

Delete these files with Titanium Software’s free utility Onyx. Launch the program, click on Cleaning in the toolbar, and then click on the Logs tab. Check System Archived Logs, and then click Execute. While you’re using Onyx, check out the many other files that the program can delete to clear up space on your Mac.
5. Weed out iTunes dupes

If you’re cavalier about how you monitor your iTunes library, you may have a lot of duplicate files. iTunes has a built-in feature to help you find duplicates, to see if you copied some files twice, or if you have the same songs on original albums and others from best-of albums.

To use this feature, choose File -> Display Duplicates. This shows all tracks that share the same name and artist. If you hold down the Option key when you select the File menu, the menu item changes to Display Exact Duplicates. This sorts for duplicates where the name, artist, and album match. Check these files carefully. You may find some that you can get rid of, saving space not only on your Mac, but also on your iPad or iPhone.

Still, iTunes’ duplicate search is limited. Doug Adams’ $15 Dupin gives you much more power to weed out duplicates, sorting by a variety of different criteria. If you add lots of music to your iTunes library, Dupin is a great way to slim it down.
6. Reset Safari

If you use Apple’s Safari, some of the program’s features can take up unnecessary space. For instance, the cache file is intended to make your browsing snappier, but can easily consume hundreds of megabytes. When it gets too big, it can actually slow down browsing. History files can make Spotlight searching sluggish. And Top Sites, Website preview images, and Website icons (favicons) can slow down the program as well.

Every now and then it’s a good idea to reset Safari. Choose Safari -> Reset Safari and check the options that interest you.

I don’t reset or delete everything—you can see my choices in the screenshot above. Choose what’s most important to you, and reset Safari every now and then to speed up your browsing and save disk space.

One last tip: have you looked in your Downloads (youruserfolder/Downloads) folder lately? You may find plenty of unneeded copies of files there too.

IDG News Service - In the wake of Gianfranco Lanci's departure as president and CEO on Thursday, Acer must move aggressively in the smartphone and tablet markets and step up its focus on enterprise PCs in order to remain a major player on the world stage, industry analysts said.

Lanci resigned from Acer over a conflict with the board about the best strategy for the company, including the importance of scale, growth, "customer value creation," and how to enhance its brand, Acer said in a statement. Acer Chairman J.T. Wang has stepped in as interim CEO until Acer finds a permanent replacement.

Analysts said Lanci's resignation may reflect a difference in opinion about how aggressively Acer should shift its focus from consumer PCs and pursue the markets for smartphones and tablet computers. Acer was one of the biggest sellers of netbooks, sales of which have been declining since Apple introduced the iPad last year.

In its statement Thursday, Acer highlighted the cautious approach it will take in the mobile device market.

"The personal computer remains the core of our business. We have built up a strong foundation and will continue to expand within, especially in the commercial PC segment. In addition, we are stepping into the new mobile device market, where we will invest cautiously and aim to become one of the leading players," Wang was quoted as saying.

The resignation came just under a week after Acer said revenue from PCs in the first quarter of fiscal 2011 would fall short of expectations due to weak demand in Western Europe and the U.S . Acer said PC revenue was showing declines of 10% from the fourth quarter of last year.

Since that announcement, Acer's stock has slumped 18% to Thursday's close of NT$60 ($2.04) and Acer founder Stan Shih has called for changes in the company's focus. Shih, who is no longer involved in daily operations at Acer, was widely quoted by Taiwanese media as saying the company should increase emphasis on smartphones and tablets and other higher end mobility products, and less on PCs.

Acer will face challenges if it clings too hard to its traditional PC business, said Jay Chou, senior research analyst at IDC. Along with the decline in the netbook business, consumer spending on PCs has slowed, he noted.

Acer has been slower to move into tablets and smartphones than rivals such as Hewlett-Packard and Dell. And those companies are less exposed to shifting market trends due to their bigger share of the enterprise PC market, where sales are relatively stable with the corporate PC refresh cycle underway, Chou said.

The popularity of the iPad, as well as rival products running Google's Android software, has caused PC makers to rethink their strategies. PC powerhouses like Dell, HP and Lenovo all started shipping tablets to complement their PC offerings, and Acer itself also started shipping tablets earlier this month.

Acer must also step up its enterprise focus and be aggressive in selling higher-margin products such as servers, Chou said. Right now, Acer's servers go mainly into small- and medium-size businesses, and it will need to build up the infrastructure to support enterprise customers.

Lanci had been a proponent of Acer's enterprise push in the past, Chou noted. Acer acquired Gateway in 2007 to improve its access to commercial channels, although the company mostly failed to expand its sales of higher-margin products.

Stephen Baker , vice president of industry analysis at NPD Techworld, said it's hard to know exactly where the disagreement lay between Lanci and the board, but he too said it may have come down to how aggressively Acer should pursue non-PC markets.

"It's pretty apparent there was a dissension over the level of commitment to the PC business," Baker said.

Netbooks had been one of the biggest growth drivers for Acer over the last few years, and replacing that growth will be a challenge, Baker said. Beyond tablets, buyers are also ditching netbooks for aggressively priced laptops with full-size screens, Baker said.

Acer offers smartphones, but they should be more tightly integrated into the company's wider operations, Baker said. A big question also remains how much of an enterprise focus Acer wants to take as it diversifies.

An Acer spokeswoman declined to comment for the story, referring to the company's press release from earlier today.

"Acer needs a period of time for adjustment," Wang said in the statement. "With the spirit of entrepreneurship, we will face new challenges and look to the future with confidence."
