Input: This unit is advertised as being the size of a credit card.  Although it is slightly larger than a credit card, it is quite powerful and versatile for small applications such as hobby devices and home-theater networks.  This device runs on a Linux system that is tailored specifically for it.  All told, I am very happy with this device, so much so that I bought a second one within a month.

Excellent Computer
