This developer kit is well put together, good looks and brains all in one tiny package. Download some sketches from the GitHub site and start hacking away on your own customized games on this platform. Good communications, documentation on the project site. The beginnings of an awesome user base and forum for exchanging ideas and suggestions. Shipping is from China, so not the next day, but not too slow either.
Got my dev environment all set up late last night and sent a few demos to the device. Can't wait to code for it. I get the feeling that the audio is a little flakey as it seems to only work sometimes. Still super excited to have something to play with before my production models show up.
Lack of documentation but its a dev kit so I guess its for the devs to learn. Otherwise a great product and I've enjoyed the development so far on the device. I've learnt so much in just a week of having the device.
