The Raspberry Pi was released recently and seems very promising in my eyes. It's a motherboard the size of a laptop hard drive, has a built in processor, memory, video, a HDMI port, 2 USB ports, an ethernet port, and a micro SD slot. It is designed to be hooked up and used on the fly. The intended OS is a linux variant though I'm sure if you got creative you could install an already existing OS on it with the right tweaks. I just got offered an order slot since these little guys sold out the first hours of their release. Check out more at www.raspberrypi.org and At CNN.com
