Three Executive-Class Laptops

Performance

With the fastest processor of the trio, it's no surprise that the Asus blew the others away in High Performance mode, with a score of 1,095 on the PerformanceTest 7.0 benchmark. That's nearly double the score of the IdeaPad or Vostro. In Battery Saving mode, its score dropped to 588.1, the slowest of the bunch.

The U36JC was also able to process and display more graphical elements when running Trainz Railroad Simulator. For instance, it revealed background details such as snow, plants and rock surfaces, which the other machines showed as plain gray.

Its eight-cell battery (the others had six-cell power packs) powered the Asus for 4 hours and 17 minutes in Battery Saving mode, by far the longest-lasting of the bunch. In High Performance mode, it ran for 3 hours and 20 minutes, roughly equal to the IdeaPad and nearly an hour longer than the Vostro. In my Wi-Fi range test, it stayed in contact with my office's router for 125 feet -- 30 feet farther than the Vostro.

At a glance

Asus U36JC A1

Asustek Computer Inc.

Price (as tested): $999

Pros: Adjustable performance, excellent battery life, two-year warranty, removable battery, USB 3.0 support

Cons: Big and heavy compared to other ultraslims, screen blanks out when switching modes

Asus has another surprise up its digital sleeve: a two-year warranty on the system, whereas the others cover their machines for half as long. The company doesn't offer a three-year warranty, but if you get the system through Amazon.com and choose the SquareTrade extension, you can get a third year of coverage for $120. Asus also provides one-year accidental damage protection, something the others don't.

My test model came with Windows 7 Home Premium (also available: Windows 7 Ultimate, Professional and Home Basic), Office 2010 Starter and a lot of extra software, including a utility for tweaking the video settings. At $999, this model costs as much as the IdeaPad U260 and about $200 more than the Vostro V130.

Bottom line

The Asus U36JC is the best equipped of the bunch and provides the raw computing power needed to get the hardest tasks done on the road, but its size and weight make it less attractive for frequent travelers. It's the executive notebook to get if you need high performance and don't mind a little extra heft.

Dell Vostro V130

The Dell Vostro V130's 0.8-in. profile makes it the thinnest of this trio of executive-class notebooks.

Roughly the same size as the MacBook Air, it is angular rather than rounded. At 12.9 x 9.0 in., its footprint is midway between the IdeaPad and Asus systems' and easily fits on an airline seat-back tray.

The lustrous aluminum case is available in red or silver; it makes for a sharp visual contrast to the softer coatings that the others have, and it feels colder to the touch. The hinges and Dell's lid logo are in demure brushed aluminum. The bottom of the V130 has no hatches and doesn't allow you to change the battery or get at the memory modules.

The version I looked at came with a nice Cole Haan leather sleeve that provides room for plenty of papers but has no handle. On its own, the sleeve costs $180.

At 3.6 lbs., the Vostro is 11 oz. heavier than the Lenovo IdeaPad U260 but 4 oz. lighter than the Asus U36JC. With its small AC adapter, the Vostro hits the road with a 4.3-lb. travel weight, more than a pound heavier than the IdeaPad's travel weight.

While the Vostro has a comfortable keyboard with 19mm keys, its metallic wrist rest can't match the comfort of the padded one on the IdeaPad. Among the three systems I looked at, it was the quietest, with a fan that hardly ever went on.

The machine is powered by an Intel 380UM Core i3 processor that runs at 1.33 GHz, slightly more than half the speed of the Asus. As a result, unlike the other two laptops, it lacks Intel's TurboBoost technology for increasing the clock speed when tasks demand it. (The Vostro can now be ordered with a Core i5 470UM processor -- the same as in the IdeaPad I tested -- but one wasn't available when I did my testing.)

The system matches the IdeaPad with 4GB of RAM and a 320GB hard drive, smaller than the 500GB drive in the Asus I tested. (A 500GB hard drive is available with some V130 models.) There's no built-in DVD drive, but Dell offers an external device for $80.

The bright screen equals the Asus laptop's in both size (13.3 in.) and resolution (1366 x 768) and is powered by the same graphics engine as the IdeaPad (Intel's GMA HD chip). Its assortment of ports is similar to the IdeaPad's, with a pair of USB 2.0 connectors but no USB 3.0 port. There are ports for VGA and HDMI, separate headphone and microphone jacks, a flash card slot and an eSATA connection for plugging in an external hard drive.

For getting online, the system offers 802.11b/g/n Wi-Fi and an Ethernet connector. Like the others, the Vostro comes with Bluetooth for connecting a keyboard or headset.

Performance

As you'd expect from a machine powered by a Core i3 processor, the V130 lagged behind the laptops with Core i5 CPUs in my performance tests. Its 601.2 score on the PassMark PerformanceTest 7.0 benchmark was faster than only the Asus in Battery Saving mode. In real-world use, its response was more sluggish than the Asus machine's in High Performance mode, particularly when moving between open windows, and it showed fewer textures and other details in the Trainz simulations.

At a glance

Vostro V130

Dell

Price (as tested): $808

Pros: Sleek aluminum case, leather bag, inexpensive, quiet operation

Cons: Short battery life, mediocre performance compared to Core i5 machines, battery and memory inaccessible

Its six-cell battery pack lasted for just 2 hours and 21 minutes on a charge, an hour short of the IdeaPad's six-cell battery and nearly two hours less than the Asus' eight-cell battery in Battery Saving mode. The system stayed connected to my office's Wi-Fi network only 95 feet from the router, 30 feet short of the Asus.

In addition to Windows 7 Professional, the V130 I tested comes with Office 2010 Starter and Trend Micro's antivirus software. (Models equipped with Ubuntu Linux or Windows 7 Home Premium are also available.) At $808, it undercuts the others by about $200. Its one-year warranty is second-best compared to the two years of service that the Asus U36JC includes; however, extending the warranty to three years adds just $80, a genuine bargain.

Bottom line

Despite an appealing aluminum case and an enviable profile, the Vostro V130 will likely disappoint mobile workers seeking the right mix of battery life and power on the road. Still, it's a beautiful system at a great price.

Lenovo IdeaPad U260

Looking more like an expensive leather portfolio than a laptop computer, Lenovo's IdeaPad U260 mixes style and power. It's the smallest and lightest of these three thin notebooks but is tied for first place in cost.

At 0.9 x 12.4 x 8.0 in., the IdeaPad is slightly thicker than the others but an inch narrower from side to side, making it the easiest to pack. Frequent fliers take note: It leaves the most room on an airline tray.

The U260 weighs just 2.9 lbs., which matches the 13-in. MacBook Air and puts it on a par with many netbooks. With its small AC adapter, the system has a travel weight of 3.4 lbs., nearly a pound lighter than the Vostro V130.

Of the three, the IdeaPad has the classiest appearance and looks the least like a notebook. Its rubberized coating has an alluring feeling and is available in clementine (orange) and mocha (brown). Open up the case and you'll see the biggest treat of all: a padded leatherette wrist rest that cushions the palms and make typing much more comfortable. Although the system has 18.8mm keys, the smallest of the bunch, the keyboard is comfortable to use.

The system I tested is powered by a Core i5 470UM processor that cruises at 1.33 GHz, but when the pressure is on, it can boost its speed to 1.86 GHz. (The entry-level model has a 1.33-GHz Core i3 processor.) The U260 takes a back seat to the power of the Asus' 2.53-GHz Core i5 460M chip.

Like the Vostro, the IdeaPad I tested came with 4GB of RAM and a 320GB hard drive; the Asus test unit had a larger 500GB drive. There's an $89 external DVD drive option, but while the drive may be useful, it doesn't match the IdeaPad's classy look.

At 12.5 in., the IdeaPad's screen is the smallest of this notebook trio, but the difference is hard to notice and it was the brightest of the three. It offers the same 1366 x 768 resolution as the others. Like the Vostro, it uses Intel's GMA HD graphics.

The ports that the IdeaPad has on tap are sufficient but not impressive, with a pair of USB 2.0 ports, VGA and HDMI connectors, and a combo headphone/microphone jack. It does without the Asus' USB 3.0 port and the more convenient separate headphone and microphone connections. Unlike the others (and unlike virtually every other notebook made today), the IdeaPad lacks an SD slot for flash memory cards.

On top of 802.11b/g/n Wi-Fi networking, the IdeaPad has an Ethernet connection and Bluetooth. Lenovo does not offer an integrated wireless data card for connecting to a cell network.

Performance

The IdeaPad was a midrange performer on just about all measures. On PassMark's PerformanceTest 7.0 benchmark, it scored a 664.5, slightly ahead of both the Vostro and the Asus in Battery Saving mode, but well behind the score of 1,095 that the Asus achieved in High Performance mode. In real-world use, the IdeaPad's performance and response times seemed on par with the Vostro's -- that is, adequate but not as fast as the Asus in High Performance mode, and it showed fewer background details in the Trainz simulations.

IdeaPad U260

Lenovo

Price (as tested): $999

Pros: Beautiful design, small size and weight, leatherette wrist rest, good balance between battery life and performance

Cons: Expensive, limited ports, no SD card slot, battery and memory inaccessible

The IdeaPad's six-cell battery can power it for 3 hours and 23 minutes, more than an hour longer than the Vostro, a virtual tie with the Asus in High Performance mode and well behind the Asus' 4:17 run time in Battery Saving mode. The IdeaPad remained connected to my office Wi-Fi router 105 feet away, 10 feet longer than the Vostro but 20 feet short of the Asus machine's mark.

Priced at $999, the IdeaPad includes Windows 7 Home Premium, Office 2010 Starter and a translucent smiley face that shows up on-screen and provides shortcuts to a variety of configuration details. It's the same price as the Asus U36JC, but it comes with a one-year warranty, a year short of the coverage that Asus provides. An extension to three years of coverage adds $80, a nice bargain.

Bottom line

If you're looking for a good compromise between size, weight and performance in a notebook that doesn't look like a notebook, the IdeaPad U260 fits the bill.

The skinny on thin notebooks

The Asus U36JC's assortment of ports (especially the USB 3.0 port), its two-year warranty and its adjustable performance settings make it a keeper. Compared to the others, however, it's big and heavy, making it too much of a good thing.

In contrast, the Dell Vostro V130 has a sleek, angular, functional design that comes with a cool leather bag at a very reasonable price. However, it lacks the battery life that I need when I travel.

And while I love the look of the Lenovo IdeaPad U260, its padded wrist rest and its marvelously small and light case, it comes up short on ports.

In the final analysis, none of these three thin machines fully met my needs and aspirations: They were either too big and heavy or too compromised. Unlike Goldilocks, I couldn't find a model that was just right, but the Lenovo IdeaPad U260 came closest to fulfilling my wants and needs on the road.
