Thanks to Little Bird Electronics I just picked up the recently released Cubieboard 2.

For less than 90 bucks Australian you get the case, 4Gb of onboard NAND flash, a USB to serial adapter, USB to power adapter (althought you should use a real wall wart), and an adapter for the onboard SATA port which can driver the 5 volt rail of a 2.5″ drive directly from the board! This blows the old iMX.53 loco into the weeds.

If you compare that to my OMAP4 based pandaboard, Go 1.1 performance is 5 to 10 % better. Not bad.
