The Chumby Hacker Board is a cool single board Linux computer that has much of the same hardware as the famous Chumby One. It's great for people who are experienced with Linux and want to have the power of a microcomputer with audio and video output while at the same time getting all the peripherals of a microcontroller such as analog-to-digital conversion, PWM outputs, sensors, bit twiddling, and broken-out GPIOs!
