Meet the UDOO Board: a development board for Android, Linux, and Arduino that can be connected to external monitors to act as a computer. In fact, the UDOO All-in-one case turns the board into an all-in-one computer. It comes with a 15″ display and can be assembled/disassembled easily.
You get easy access to the UDOO board and can try different Arduino shields. The back panel is removable. Ships in October.
