It's the Toshiba Libretto U105. There are smaller windows machines, but none in the traditional laptop form. After a couple weeks of practice the keyboard is actually pretty good. I can probably type 80-90% as fast as I can on a full size keyboard. If you get one, make sure to get the U105. The only difference between it and the U100 is that it has a very useful DVD/CD reader / writer. The best thing about it is that it has a high resolution 1280x768 screen, which is better than most 15" and 17" laptops.
