Recently, NorhTec came up with a SoC (System On A Chip). They have put it inside a computer keyboard and called it the Surfboard. The results will remind anyone who had a Vic 20 or Commodore 64. The entire computer is in the keyboard (it pulls 5 watts. The C64 pulled 10). 512M of memory, 1G CPU, composite video out.
Linux based Surfboard? $99
Windows XP Surfboard? $149
