I'm a little late coming to this, but I ran across a blog by Dave Aiello at Operation Gadget about a three-part series on developing for the Nokia N800 Internet Tablet at IBM developerWorks.

The series was written by Peter Seebach. Part 1: Developing for the Nokia N800, part 2: Accessing the Nokia N800 camera, and part 3: Auto-uploading Nokia N800 photos.

Thanks to Dave for the blog and thanks to Peter for the series! Looks great! I'll post on it once I get a chance to dig into it.
