Nokia N800 Internet Tablet

The Nokia N800 is a major upgrade over the 770. The wi-fi, reviewers say, is amazingly powerful and can find hotspots other devices can’t. There’s also a built-in keyboard that senses whether you’re using the stylus or fingers, and changes size accordingly. Plus, you can get open source apps for it at Maemo.org.

Price is a quite reasonable US $399.
