You have to take only a couple of business trips or vacations with a 6-pound laptop in tow before you start thinking about switching to a PC with a little less meat on its bones.
Although 14- and 15-inch all-purpose laptops are abundant and often inexpensive, just throw one into your backpack or briefcase and lug it around for a few days--your shoulders will soon beg for mercy. These days, fortunately, you can find plenty of laptops on the market that are slimmer, lighter, and more powerful than almost anything that you could have bought just a few years ago.
What qualifies as a "lightweight laptop"? We drew the line at 4 pounds. There's a marked difference in design, features, and feel between laptops under that weight and their heavier friends. It may not seem like much, but a pound or two can make a big difference. Consider the heft of a pint of water: 1 pound. The difference between the lightweight laptops featured here and your run-of-the-mill 5.5-pounder is the equivalent of two (or two-and-a-half) extra pints of water in your laptop bag. It gets tiresome pretty fast.
Of course, laptops that are more Olive Oyl than Bluto come with a few compromises. Giving up weight can mean giving up performance, battery life, and certain other capabilities. Most laptops that weigh less than 4 pounds lack optical drives, so forget about burning DVDs or watching Blu-ray movies without an external USB drive.
They also tend to be thinner, leaving less room for larger, longer-running batteries, and for heat sinks and fans to dissipate the heat from high-power processors, which in turn means limited processing power. Nor is there room for a high-power discrete graphics card, so gaming enthusiasts are out of luck. Finally, expect to pay a little more for a thin-and-light laptop, relative to the performance received. Sure, you can find cheap laptops under 4 pounds, but at any given price, you'll get more performance, storage space, and features if you're willing to deal with some extra weight.
Truly light laptops rarely have a screen larger than 13 inches, but they otherwise come in a variety of styles, sizes, and prices.

If superslim is your preference, look no further than the Samsung Series 9, the latest PC to seriously challenge Apple's MacBook Air for slim-computing dominance. Business users especially interested in usability will want to focus on the ThinkPad X220, which maintains Lenovo's excellent, long-running standards for keyboard quality and management features.
And for the more style-minded among us, Lenovo has a sleeker unit in the IdeaPad U260. Meanwhile, Sony's Z-Series VPC-Z137GX/S is a pricey alternative aimed at business executives who want it all, including a decent discrete graphics chip.
If you're on a tighter budget, the tiny size of Lenovo's ThinkPad X120e netbook should fit the bill. It's powered by AMD's Fusion E-series processor, giving it performance that's a step above the typical Intel Atom-powered netbook.
Let's look at these ultralight laptops in alphabetical order.
Lenovo's IdeaPad U260: Unexpected Style
Despite generations of sober-looking, utilitarian forebears and a name that suggests a bad World War II submarine movie, Lenovo's $1199 IdeaPad U260 goes where the company's laptops never went before--into the queue for style and design awards.
And the U260 gives Apple and Sony something to think about. When closed and viewed from the back, with its dark copper shell (Lenovo calls the color "mocha brown") covering the black main body, this 0.75-inch-thick ultraportable laptop resembles an extravagantly bound book- or pad-holder.
When opened, the IdeaPad U260 presents you with an all-black, minimally populated keyboard deck consisting of a smallish power button, an ambient light sensor that adjusts display brightness automatically, a tiny OneKey system recovery button (accessible only if you use a pointy object), the best Chiclet-style keyboard I've ever typed on, and an equally elegant touchpad with smooth-operating buttons. In a break with tradition, Lenovo does not include an eraserhead or nubbin pointing device.
Style aside, the U260 earned mixed results in PCWorld Labs tests. Our review unit had an Intel Core i5 470UM CPU, 4GB of DDR3 system memory, and a 12.5-inch color display with 1388 by 766 resolution. But the 320GB hard drive spins at just 5400 rpm, which undoubtedly helped hold the U260's WorldBench 6 score to a pedestrian 75. (An update to one of Intel's Sandy Bridge CPUs would certainly boost the laptop's performance.)
Gaming frame rates on our test machine were in the teens (or worse), owing to Intel's integrated graphics. On the other hand, every video we tried played smoothly, even at 1080p. Audio quality is so-so, and rather quiet through the speaker.
Your connection options consist of two USB 2.0 ports, VGA and HDMI video outputs, an AC jack, a gigabit ethernet port, and a single combination microphone/headphone jack. The laptop has no internal optical drive, and the wireless is 802.11n.
Lenovo includes 64-bit Windows 7 Home Premium as the operating system, but no productivity software. You also get a VeriFace facial recognition utility that's quite cool, as well as a shock sensor and the CyberLink Webcam utility.
The U260 is an average performer overall, but its top-of-the-line ergonomics more than compensates for that. My main disappointment is the lack of an option for a faster hard disk or a solid-state drive, to improve performance.

Lenovo's ThinkPad x120e: A Superfast Netbook for Business
Lenovo calls its ThinkPad X120e an ultraportable-and its AMD Fusion CPU certainly endows the laptop with much more muscle than past netbooks have exhibited. But it's nowhere near as fast as the average Intel Core CPU-based ultraportable. Given the choice to characterize the X120e as an underpowered ultraportable or as a wonderful netbook, I'm going with the latter.
Lenovo has done a magnificent job of giving the keyboard a full-size feel, but the 1366-by-768-resolution, 11.6-inch display suffers compared with some other models' larger screens. Lenovo, however, is king of the keyboard, and the X120e has the best netbook keyboard ever--nothing else comes close. The feel is magnificent. The touchpad is comfortable and perfectly responsive, and the company includes a TrackPoint eraserhead cursor control.
The ThinkPad X120e comes in various configurations, starting at $399 for an E-250 Fusion CPU, 2GB of memory, and a 250GB, 5400-rpm hard drive. Our X120e test system came equipped with the slightly faster E-350 CPU, 4GB of memory, and a 300GB, 7200-rpm hard drive. Those burlier components carried the X120e to a WorldBench 6 score of 57--far higher than traditional netbooks receive, but lower than a typical, pricier ultraportable. (Our review unit would cost $650--pretty steep for a netbook.)
Video performance ranges from excellent to mediocre. With codecs that its Radeon HD 6310 graphics hardware supports, it plays 1080p video smoothly. But with codecs handled by the CPU alone, it's limited to 720p, not always smoothly. Gaming frame rates approached playable, falling just shy of 30 frames per second in Unreal Tournament at 800 by 600 at medium resolution.
The X120e carries the netbook-standard three USB 2.0 ports, and both VGA and HDMI video outputs. Its ethernet capability supports gigabit speeds, you get Bluetooth on board, and you can choose between b/g/n and a/b/g/n wireless.
A tad larger than the average netbook at 11.1 inches wide by 7.45 inches deep (add about 0.75 inch for a six-cell battery) and 1.16 inches thick, the X120e weighs 2.93 pounds (with a three-cell battery) or 3.31 pounds (with a six-cell pack). A six-cell battery powered our test unit for nearly 5.5 hours--impressively long.
Our test system came with Windows 7 Professional, but you may choose Home Premium 32-bit or 64-bit, instead. Office 2010 Starter is on board; Norton Internet Security is an option.
The X120e is not an ultraportable: Its screen is too small, and its performance too slow. But it's the best netbook going. One typing session will convince you that this model is more than worth its $450 starting price.

Lenovo ThinkPad X220: A Best-of-Breed Ultraportable
Lenovo's ThinkPad X220, which replaces the X201 model, is sure to be a hit with ThinkPad fans--and most everyone else. It is fast and light, has a great 12.5-inch display, and continues the company's enviable tradition of superb input ergonomics, offering an innovative buttonless touchpad and a long-stroke keyboard. It also provides excellent battery life--up to a whopping 23 hours with a bottom-mounted battery slice. The downside? Not much--mainly a boxy, businesslike look.
Exact prices for all of the ThinkPad X220's configurations are unavailable at this time: The starting price should be $979, going up with better CPUs, solid-state drives instead of standard hard-disk drives, and more RAM. CPUs range from an Intel Core i3 to a Core i7, the unit accepts up to 8GB of memory, and storage options start with a 160GB HDD and end with a 160GB SSD.
Our $1299 test model--with its 2.5GHz Core i5-2520M processor, 4GB of DDR3 system memory, and 7200-rpm, 320GB hard drive--turned in an outstanding WorldBench 6 score of 122. And its integrated Intel HD Graphics 3000 GPU managed playable frame rates in some lighter gaming tests; 1080p movies, even the high-bit-rate variety, play smoothly.
Some of the keys, such as the extra-large <Esc> and <Del> keys above the main alphabetical keys, are a tad odd. These keys don't hinder your typing, however; they help it. The long-throw feel of the keyboard is excellent. The touchpad has a buttonless design-you press down on the left or right front edge to click. Two normal buttons sit above the touchpad, and you also get Lenovo's TrackPoint eraserhead pointing device.
The X220's battery life is outstanding. Our test machine, with its six-cell battery, ran for a cool 7 hours, 15 minutes. You can opt for a three-cell or nine-cell main battery, for less weight or a longer run time, and add a bottom-mounted $179 battery slice.
The ports and connectivity on the X220 are top-notch. The system has three USB ports, one of which is powered (for charging cell phones and the like) even when the laptop isn't turned on. With the i7 CPU, one port can optionally be USB 3.0. You'll also find an ExpressCard slot, an SD Card slot, a Wi-Fi switch, a VGA port, and a gigabit ethernet port. A dock is available with a multiformat burner, Bluetooth is on board, and the Wi-Fi is dual-band 802.11n (2.4GHz and 5GHz). Our test laptop arrived with IBM's biometric finger-swipe sensor to facilitate security.
But be wary of the many "value added" applications and unnecessary background processes. The Windows 7 Professional operating system has just about every software feature you need for a laptop, yet on our machine a quick glance at the Windows Task Manager revealed nearly 90 processes at work and almost 30 percent memory usage--without a single user application running. Trial versions of Norton Internet Security and Microsoft Office 2010 Starter come bundled.
ThinkPad users won't find anything mind-blowingly different here, but the improvements are noticeable, and all of them enhance usability. The Lenovo ThinkPad X220 is in many ways the best thing going in an ultraportable.

Samsung Series 9: A Real MacBook Air Competitor
At less than 3 pounds and 0.7 inch thick, Samsung's Series 9 laptop challenges Apple's MacBook Air for the ultraslim limelight. At a starting price of $1649 (compared with Apple's $1299), the Series 9 is costlier than the 13-inch MacBook Air, but it offers generally superior hardware and is eminently usable.
The biggest advantage that Samsung's slim wonder has over the Air is in the processor. Apple is still using a two-generations-old Core 2 Duo, while the Series 9 comes equipped with a new "Sandy Bridge" Core i5 2537M. So even though the default clock speed of the Air is 1.86GHz and the ultra-low-voltage CPU in the Series 9 is only 1.4GHz, the Series 9 is actually a bit faster: It earned a WorldBench 6 score of 103, while the 13-inch MacBook Air scored 90. Also, Samsung includes 4GB of RAM.
The Series 9's battery life is quite decent for a laptop this thin: 5.5 hours in our battery run-down tests, which is on a par with many thicker, heavier ultraportables, and about half an hour longer than the 13-inch MacBook Air. The Series 9 comes standard with a 128GB solid-state drive, as the Air does, and this enables the system to feel responsive and quick, to boot up fast, and to resume Windows in less than 3 seconds when you open the lid.
The Series 9 falls a bit short in 3D gaming, relying on Intel's HD Graphics 3000 to push pixels; the GPU isn't powerful enough to run the latest games without severely compromising visual quality. But the integrated graphics does a great job with video decoding, so even high-def material plays smoothly.
