WAY to big for me, but I like the concept, especially the screen looks cool. I hope they are successful, but I won't support them. For basic coding I've got my Gamebuino.
Yeah, that d-pad looks horrible. It might be okay for testing out the latest thing you've coded up, but I can't imagine myself testing out other people's projects using it, or playing anything for any length of time to be honest. Other than that it looks like an interesting project though, to hack about with.
Hmm... for me its a bit overpriced and the CPU could be faster and/or an FPGA (It looks like its too slow for alpha blending). But the Display could look really interesting and bright. I wonder how my Avatar would look on it. *googles for LED Matrix*
Edit: Looks like they're using this LED Matrix.
Edit2: with the Proper CPU Power these Matrixes look really cool:
