The nobounds appeared to use a Windows XP computer running the same program as on the tablet.
It was smoke and mirrors, look closely at the video and note the XP titlebars and Full resolution 3d on desktop and extremely cutdown limited version on the tablet.

If it was marketed as a tablet/desktop live update synced program I would be wooping to the sky about it because its a powerful principle.

I have drawn up plans for something similar via liqbase: initial testing on a desktop shows the core system will work with tweaks, all that would be needed would be a communications protocol between the machines to sync actions made on the tablet
