This tutorial will teach you how to create your own handheld linux terminal with built in screen, QWERTY thumb keyboard and battery. It has four passive USB ports for expansion and extra connectivity. It’s super portable and is about the size of a Nintendo DS (if slightly thicker).

“It’s basically a full handheld linux system that can do almost everything a normal sized computer can do. It’s not going to destroy any benchmark tests, so it’s best suited to command line stuff. Since this is the case, it’s actually a pretty good tool for learning the command line interface as well as basic scripting.” — n-o-d-e.net
