[Wlug] TinyArcade and Arduboy

I've been playing around with the Tiny Arcade by Tiny Circuits. It's been a lot of fun programming. The initial development of Color Monster is documented here: http://identicalsoftware.com/games/colormonster The new Pocket Arcade has me really interested but it isn't available yet. I stumbled across the Arduboy. (Stumbled again? I'm pretty sure I saw the kickstarter and decided against it.) Does anyone have one? What do they think of it? I think it isn't quite what I want for a system. Seems like it can be annoying to upload a new game onto the system. While I had fun with the TinyScreen Video Game Kit, I like the microsd card of the Tiny Arcade so you can have multiple games available.
