If all you are looking for is a small portable email client/web browser for the road, check ebay for a really small/cheap laptop.. aka: the thinkpad 240. It is fully supported by openbsd extremely easily. An out of the box install of openbsd easily runs on the 240 without much configuration needed. These little laptops are cheap and reliable. The only thing which kinda sucks... when playing music, if you use headphones, you can hear the hard drive access noises since the laptop is so small.
That doesn't bother me much though as I whore the ipod everywhere I go anyway. "I'm hoping to use a zaurus as a full featured browser, email client while on the road...."
