PC World has a great article on alternatives to the limited, but sexy, MacBook Air. One of the alternatives they point to is the Fujitsu T2010 Tablet PC, which we featured in this InkShow.

In our tests, the ultra slim and light Fujitsu LifeBook T2010 convertible tablet offered one of the best battery performances we've seen--lasting nearly 7 hours on a nine-cell battery.

The T2010 scored points for its versatile 12.1-inch screen, which is designed to be easily viewed indoors and out. The antiglare coating made the screen a bit difficult to read in direct sunlight, however. The keyboard layout is excellent. The tablet features one PC Card slot; two USB ports; Wi-Fi and Bluetooth; and an integrated Smart Card slot for security. You don't get a built-in optical drive, however.

Update: Walt Mossberg gives us a sneak peek at Lenovo's alternative to the MacBook Air, the X300. Unfortunately, the X300 is not a Tablet PC, but it is a fully spec'd ultra-portable coming in at 3.12 lbs.
