Review: Lenovo ThinkPad T400s multitouch screen

PC World - We've already reviewed Lenovo's ThinkPad T400s laptop, a reasonably slim and powerful corporate raider. We love it, it works, and it's riding high atop our chart for the best all-purpose laptops currently kicking around. So how could Lenovo improve on that? By adding a multitouch panel.

Today, Lenovo is bringing touchscreens to the T400s and to the X200; the new feature adds $250 to each machine's price, making them $1999 and $1654, respectively. The company was able to send us an early production unit so that we could check out its backlit, WXGA+, 1440-by-900-pixel LED panel.

We can't give a full review of the T400s's multitouch performance in Windows 7 for the simple reason that the drivers are anything but final and the list of caveats is longer than a grocery list. In short, it works, but it isn't perfect. So consider this a superquick guided tour of a single aspect of a laptop.

Simple Tap is the software that shows off everything. You use two fingers and tap anywhere on the screen (or just hit the big red button that camps near the top) to open a set of tiles that overlay your desktop. Said tapping will require you to hold the back of the display and touch the screen with a little more gusto, but for the most part you'll be in business.

Several preconfigured hardware tiles provide the major shortcuts you're likely to use. Among them are icons for adjusting the screen brightness, toggling the LED "reading" light, changing volume, controlling Wi-Fi, setting the Webcam, activating hibernate, or just locking the computer.

You also have the option to create your own custom shortcut tiles, whether you want to your launch your browser, say, or a specific Excel spreadsheet. And if you don't like having a grid floating over your desktop, you can arrange the tiles anywhere on your screen. Simple Tap will be available for download on October 22 -- gee, I wonder why.

Though the gesture-based commands work, I found the test T400s a little sluggish. Zooming in and out of Web pages took longer than expected, and I noticed a couple-second lag between pinching and seeing the on-screen results. The effect is a bit jarring--and it makes hitting the desired spot difficult.

The Windows 7 drivers haven't been finalized--and Simple Tap software is in beta--which explains why many of the slider-adjustable features (such as volume and brightness) simply weren't working. I can say, however, that the screen coating looks better than I expected. Tablet PCs normally look dim and drab because of the display. Even though I doubt that the touch panel I've been testing is final, its colors seem to pop reasonably well provided that I use it at the right viewing angle. My only wish is that the display would lock into a good viewing angle and be a little firmer so that I don't need to brace the back of the lid with my hand when I tap the touchscreen.

I'm curious about how the new screen might affect battery life, too. Unfortunately, I can't give a final answer on our battery-life tests, due to time constraints in getting this story up. However, in basic use (Web surfing and typing Word documents) the machine's six-cell battery lasted about 4 hours.

In short order, you'll start to hear plenty of laptop vendors trumpeting multitouch capabilities. (Heck, stay tuned later today.) For many a laptop, I'm expecting to see touchscreens as just another drop-down configuration option at various vendor sites--sooner rather than later. Right now, though, it's the T400s's moment in the spotlight. I'll try to give a more definitive word when a final version of this laptop shows up at the PC World Lab.
