Sony Duo 11 Ultrabook review: Blurring the line between tablet and laptop


Unpacking the Sony Duo 11 (aka the SVD1123CXB) reveals what appears to be a tablet; no keyboard is immediately visible. Yet when you pick it up, it seems a little hefty for a tablet. What's going on here? Well, the Duo 11 is not just a tablet. Lifting up the top edge tilts the display and reveals a sliding keyboard hidden beneath the panel.
Welcome to the world of Windows 8 sliders. The Duo 11 keeps its keyboard tucked underneath the tablet's bottom chassis—it's there when you need it, but you can hide it away when you don't.

The Duo 11 modes

The Duo 11 weighs in at 2 pounds, 13 ounces, decidedly on the light side for an Ultrabook. The 11.6-inch screen offers a full 1920-by-1080-pixel IPS touchscreen panel that provides good image quality and color fidelity. Sony also built a full Wacom digitizer into the touchscreen, complete with a stylus supporting 256 levels of pressure sensitivity. Artists will appreciate the digitizer, but Sony didn't think to include a slot to store the stylus in the body of the unit, so you'll need to keep track of it as you travel.

Laptops for Back-to-School: How to Make the Right Choice


Students have different budgets and needs. Picking the right laptop will save both money and frustration.

It’s back-to-school time, and retailers are inundating everyone with back-to-school specials, ads, email promos, and even direct-mail offers, all promising the best possible computer deal for your student. The problem is that many of these deals focus on some generic student, failing to address the needs or wants of individual students. Sure, the bargains often look attractive, but before you whip out your credit card, you should spend a little time with your student to figure out what they need.
College students, for example, don't have an easy time buying a computer for school. Budgets can be tight. Space is at a premium—particularly today, when colleges are cramming three bodies into rooms designed for just a pair of students. And computer needs may change due to class requirements.
That’s not to say that high school students don’t have their own needs. Nowadays, high school juniors and seniors face more-demanding curricula, with an increased homework load plus a growing need for collaboration and teamwork. They may have more space than college students, but not necessarily more budget.
Since today’s students are more mobile and more connected than ever, laptops are typically a better choice for students than desktop PCs. Students who require a larger display can always connect to one at their home desk.
My younger daughter, Emily, is heading off to college this year, and we just finished researching and buying a laptop. In addition to talking about technology and products, I’ll share some of our experiences and thought processes.

Before Buying: Research

Laptops for Back-to-School: How to Make the Right ChoiceMy college-bound daughter, Emily, liked the usability and design of the Dell XPS 14.First of all, PCWorld is an excellent tool for researching laptops. Our laptop reviews give you an edge, helping you zero in on the models you should consider. You can sort the reviews by price, size, brand, and other features.
Don’t forget to check with the college or university your child will be attending. Schools often have listings of deals from different manufacturers, including discounts that may not be readily visible on the manufacturers' websites.
Also check any specific requirements the university has for hardware, software, or accessories. While most colleges may be brand agnostic, a few support Apple or Windows exclusively. Other colleges restrict certain types of hardware, forbidding items such as routers or network-attached storage. You’ll want to know about such conditions before you buy anything.

Work Versus Play: A Reality Check

Sometimes it seems like the ideal laptop for a student weighs under 4 pounds, sports a 24-inch display, carries 5TB of storage, and has a 175W graphics processor. That’s an impossible mix, of course, so your first task is to talk with your student and do a reality check. Emily is a good example. She’s a pretty serious PC gamer; she likes playing MMOs and PC-based role-playing games that often demand serious graphics horsepower.
You need to impress on your student that a laptop for school should be optimized for the work, not the play. When we bought a school laptop for my older daughter, Elizabeth, we didn’t quite grasp this concept. She ended up with a 15.6-inch laptop that had a decent mobile GPU and a very nice screen—and weighed nearly 7 pounds. She came to dread lugging it around, even when she needed it for class. Next time around, she’ll get something lighter, as she has come to realize that she doesn’t really use her laptop for gaming; her most demanding application is photo editing. Classes change, and so do hobbies.
Laptops for Back-to-School: How to Make the Right ChoiceThe HP Envy 4 turned out to be a no-go because the touchpad buttons required a lot of force to press.
I told Emily that if gaming was truly important to her, she should consider making room for a desktop system of some kind. For a school computer, mobility was more important than the ability to run Mass Effect 3 at high detail levels, I said. On the other hand, she wasn’t willing to sacrifice usabilityfor sheer portability. (I’ll get to what that means shortly.)
She’s also a pretty good touch typist, so both keyboard and touchpad feel are important to her. Performance is a high priority, too—but when Emily talks about performance, she really means “responsiveness.” So although raw CPU or graphics horsepower may not be critical, having adequate memory to allow a lot of simultaneously open windows and browser tabs is pretty important.
Ask your student several questions: What types of classes are they taking? Will the emphasis be on math or writing, or will it be a blend of both? Online collaboration is more common now than in past years, so reliable networking capabilities and a good webcam are must-haves, too.
Let’s run down a list of key considerations.
  • Budget: Before you begin shopping, set your budget. That will narrow the choices substantially. Try not to set the budget too low. Newspaper ads are often full of $499 laptops, but those models tend to be bulky, with less-than-robust plastic shells. The sweet spot for performance and durability seems to be between $800 and $1200 these days. Spending more than that will get you nice luxuries, such as a large solid-state drive or a beefier CPU, but typically those aren't necessities.
  • Mobility: This term means different things to different students. Some people are willing to lug around 7 pounds of laptop all day long, but most aren’t. Remember to factor in the weight of the charger.
  • Battery life: A high-performance laptop will do little good if the battery dies after a couple of hours. You can’t always find wall power on the go.
  • Usability: A good keyboard and a usable touchpad are both important, but the feel is a personal choice. Some folks are willing to give up a little tactile feedback in the keyboard if it saves them a pound of weight.
  • Display: The most common LCD-panel resolution today is 1366 by 768. But if you can find a laptop with a good 1600-by-900-pixel screen or even a 1080p display, that machine becomes even more usable, particularly for Windows 7 and the upcoming Windows 8.
  • Mac versus PC: This is another personal choice. My older daughter might have been perfectly happy with Mac OS X, but Emily was adamant about getting a Windows-based system.
  • Storage: Since laptops are often a student’s only PC, adequate storage is essential. A 128GB SSD might be ideal for a business road warrior connected to corporate servers, but students will want their music, their photos, and even their games on the one system. Typically that means picking a laptop with a large hard drive over one with a smaller SSD.
  • Secondary storage: In addition to primary storage, your student will need backup storage. Although backing up to cloud services is an interesting option, having a portable, bus-powered hard drive is crucial.
  • Connectivity: If the laptop lacks an ethernet jack, as some ultraportable systems do these days, you’ll want a USB-to-ethernet adapter. While most universities now have Wi-Fi in most places, not all of them do. For example, Emily’s dorm rooms require a wired ethernet connection, even though Wi-Fi is available on the main campus.
  • Support: Springing for an extra warranty is worthwhile. First-year students in particular tend to bang up their laptops, spill coffee on them, lose them. Extra support services, such as an extended warranty that also covers accidental damage, can be indispensable. Many companies now also offer location tracking, such as Intel Anti-Theft technology, Lojack for Laptops, or Apple’s Find My Mac. A tracking feature could be a lifesaver if your student leaves the laptop in a coffee shop or if someone steals it.

Don't Sweat the Jargon

You'll find laptop ads full of terms like "turbo-boost," "3rd-generation Core processor," "400-nit brightness," and other jargon. Most PCWorld readers already understand a fair amount of this stuff, but you don't need to obsess over the raw spec details. In a mobile PC, usability, battery life, and ease of transport are much more important.

Intel Targets Low-price Laptops With Celeron Chip Refresh


Intel has started shipping four new Celeron chips intended for low-priced laptops as it gears up for the back-to-school shopping season.
The new dual-core Celeron 877 and 847 chips, based on the Sandy Bridge microarchitecture, are part of the same family of processors that appeared in low-priced laptops in the US$200 to $500 range during last year's holiday shopping season. The 877, in particular, will allow vendors to cut prices while boosting performance.
The new Celeron chips have integrated graphics and virtualization support. The processors do not have some features available on Intel's faster Core series processors such as Quick Sync video acceleration or Turbo Boost, in which cores can be disabled or sped up depending on processing requirements.
The Celeron 877 is priced at $86 in quantities of 1,000 units and has a clock speed of 1.4GHz. That is a speed increase from the previous fastest Celeron in that line up, the 867, which ran at 1.3GHz and cost $134.
The new Celeron 847 has a clock speed of 1.1GHz and is priced at $70 in quantities of 1,000.
Intel also started shipping the dual-core Celeron M B820 chip, which has a clock speed of 1.7GHz, and is priced at $86 in quantities of 1,000. A faster version, the Celeron M B830 running at 1.8GHz, is expected later this quarter and will likely be priced higher than the B820.
The other new chip is the single-core B730 runs at 1.8GHz and is priced at $70 in quantities of 1,000.
Intel in its CPU reference chart also detailed new Pentium chips at clock speeds from 2.2GHz to 2.6GHz that will ship later this quarter. The Pentium G645 chips runs at 2.5GHz, the G620 chip at 2.6GHz and the G620T chip from 2.2GHz. Prices were not available for the chips.

Meet the New PC: Not the Same as the Old PC


Meet the New PC: Not the Same as the Old PCMicrosoft SurfaceRevolutions are chaotic: They upset the status quo, and leave old ways of doing things behind. The PC, once the spearhead of the personal digital revolution, may seem antiquated alongside sexy new tablets and smartphones. In reality, however, the PC is an intimate participant in the current revolution, changing its own nature to respond to new usage models and a new generation of users. If anything, Microsoft’s recent announcement of the Surface--a Windows 8 PC posing as a tablet--demonstrates the PC’s flexibility and relevance in the modern digital era.
The new computing revolution is upon us, driven by a legion of users and developers creating new ways of interacting with data, and with one another, in an always-connected world. And the new PC has stepped up to address the needs of users and application builders who have never known a world without the Internet. Apple and Microsoft are creating uniform operating environments, enabling a seamless transition from mobile phone to PC or Mac, all connected via cloud services. Windows 8 is leading the way, with the same OS core at the heart of Windows Phone 8, Windows RT, and Windows 8 on the PC.
The PC is undergoing its most radical makeover since the advent of the IBM PC three decades ago. Pundits like to call this the "post-PC era," but the PC remains the hub of our digital lives. Call it a PC, call it an Ultrabook, call it Surface--it’s still a personal computer to the core.

The New Revolution

Always-on connectivity, the cloud, and easy mobility define today’s personal technology revolution. Users have had a role in the revolution, embracing digital media consumption instead of viewing digital devices as mere tools. Users of smartphones and tablets--in particular, iPhone and iPad owners--blazed the trail. As in the early age of the personal computer (before the IBM PC), the nascent smartphone market was highly fragmented, with diverging views of what users wanted. These days, after the rise of the iPhone, almost all phones look startlingly similar. Having a data plan with your smartphone is now mainstream; it wasn’t always that way.
Meet the New PC: Not the Same as the Old PCUltrabooksAfter a slow start, PC makers are now embracing the change. Inspired by the MacBook Air, Intel’s Ultrabook program is driving mainstream adoption of ultrathin, ultraportable PCs that make far fewer compromises than the netbooks of recent memory. The majority of these designs--including Apple’s--are based on Intel hardware.
The new generation of Ultrabooks has been relatively slow to adopt the always-connected model, as surprisingly few units are shipping with built-in cellular broadband. As true 4G networks become more widespread, that might change, especially as cloud storage becomes more integral to the operating system. Apple is already pursuing this idea with iCloud, and Microsoft will be integrating its SkyDrive service into Windows 8.
Ultrabooks are only one response to the changing market, though. Microsoft’s new Surface tablets show how PCs are evolving in other directions. The Surface RT model is locked into Microsoft’s app store, much as Apple’s iPad is locked into iTunes. But the Surface Pro is really an ultrathin PC in a tablet skin, with a fully functional Windows desktop and the ability to run most Windows applications.

Cloudy, With a Chance of Apps

While the notion of running software from the cloud isn’t new, it is gathering steam. Google has led the charge, and Google Docs has seen rapid adoption. Microsoft has been pitching Office 365 (a collection of hosted productivity apps) to businesses. Even games are running on the cloud, with companies such as Gaikai and OnLive offering games on cloud servers and delivering interactive streams to user desktops.

Unified Operating Environments

Meet the New PC: Not the Same as the Old PCBoth Apple and Microsoft are driving toward unified operating environments across smartphone, tablet, and personal computing platforms. In some ways, Microsoft is ahead of the curve. Windows 8, Windows RT, and Windows Phone 8 will offer nearly identical user experiences. With the release of iOS 6 and Mac OS X Mountain Lion, Apple is taking another step along the road to user-experience integration.
Not all users are on board with unified environments, though. Windows 8 seems to be particularly polarizing. Running the Metro interface on a desktop system, or even a laptop PC, seemed to be a baffling decision on Microsoft's part, until the announcement of the Surface. Windows 8 and the Surface are closely intertwined, and it’s clearly the direction Microsoft wants to take the operating system--and its users.

Taiwan Worries New Apple Patent Could Target Ultrabooks


A Taiwanese government office is warning local PC vendors of a new Apple patent for its MacBook Air that could be used in legal action to try and stop the sale of ultrabook models.
Last month, Apple received a U.S. patent for the exterior wedge-like design of its MacBook Air devices. The intellectual property office of Taiwan's Ministry of Economic Affairs, however, worries the patent could create legal problems for ultrabooks, given that the laptops also feature thin and light designs similar to the MacBook Air.
"We are recommending that PC vendors be careful," said Xue Shuhua, a public relations staff member with the office on Wednesday.
MacBook Air
Xue noted that Apple has already targeted Taiwanese smartphone vendor HTC in several patent-related complaints that have sought to ban the import of the company's phone into the U.S. The legal battles have recently delayed the shipments of HTC's newest smartphones to the country, the result of a U.S. International Trade Commission ruling.
Acer Aspire
"Companies that manufacture ultrabooks should avoid the Apple patent when producing their products," Xue said. The office plans to hold a meeting with Taiwan's PC manufacturers, but has yet to decide when or which companies to talk with.
Taiwan's PC vendors include Acer and Asus, both of which sell ultrabook models in the U.S.
Acer said in a statement, "Apple's patent on the teardrop profile design is different to Acer's ultrabook design. Hence, currently, the patent has no impact on Acer."
Asus ultrabook
Asus could not be reached for comment.
The warning is just the latest move by Taiwan's electronics industry to try and fend off patent disputes. Last year, a major Taiwanese research institute announced it was creating an intellectual property "bank" to acquire patents in Taiwan and abroad as a way to protect vendors from further patent infringement lawsuits.
Intel, which defined the ultrabooks category, declined to comment.
