To be honest, as a games platform running android I have no interest in it, but if they or NVidia actually provided some real working accelerated video drivers for linux this would make a great piece of hardware for XBMC/VDR use.
I already have a Tegra2 desktop machine which was meant to fill that purpose, unfortunately between NVidias broken hardware and their total lack of linux drivers it's nothing but a very small, silent door stop
As a gaming device it becomes a Nintendo also ran with a standard game pad. Most of the Android games I've actually played for longer than it took to install them worked because of the touch screen interface and the casual game play style. The FPS/Racers with the tilt control or on-screen joypad are just poor and if I want them on a big screen then I'll use my PS3 not a Tegra3 based device.
Between the Raspberry Pi, the Cotton Candy and the 3rd device I can't remember there are already 3 machines capable of doing everything this box can. The problem as usual is driver support and a promise of features working in the future when the drivers are ready, while releasing a device which isn't fully working while people will throw money at it.
If Google ever get their act together with the Google TV devices, then I can see this also becoming an also ran product. I bet the next Google TV device will have a control pad available.
I also have more confidence that the Apple Ios TV will hit the market and work before this does. Android has been losing developers to Apple, purely because the costs developing for and supporting the Apple devices are lower than for the Android devices.
