Chip Computer
You won't be running Photoshop on it any time soon, but for the price, that's not surprising. Instead, the Chip Computer is aimed at tinkerers and others looking for a bare-bones system that can get you on the web, play media, and even run rudimentary games. This tiny single-board system is powered by a 1Ghz processor, and offers 512MB of RAM, 4GB of storage, Wi-Fi and Bluetooth built-in, and an open source operating system. In addition, you can add-on VGA or HDMI adapters, run it off a battery pack, or even install it into a pre-configured, Game Boy-like case for on-the-go use. Not bad for something roughly the size of a couple AA batteries that costs less than a good pizza.
