We just released both of our current Android games -- Riptide GP and Shine Runner -- on the Barnes and Noble App Store for Nook.

Seriously, the new Nook tablet is a pretty impressive piece of hardware. It packs a lot of punch for $199. At least, it runs both of our games well, and that's no easy feat seeing as how they're packed so full of 3D physicsy goodness.
The old Nook Color ain't so bad, either, and the price is seriously right at $169. I mean, dang-- that's like the price of a large popcorn at the movies these days. Well, almost. But you can't race hydro jets in a bucket of popcorn.
