This sounds great! Hopefully Wandboard will meet their time frames and start shipping in mass quantity soon. It looks like today they released a Jellybean (Android) and Ubuntu preview image.

I do not see a US distributor listed? ------------------------------------------------------------------------ dustinsterk's Profile: http://forums.slimdevices.com/member.php?userid=19649 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
