I'm impressed with my G1 out-of-the-box (coming from a T-Mo Dash). And as long as there are significant improvements I will be delighted with it.
I downloaded, installed it, and manage to compile the sample code pretty easily. Reminds me a bit of ForwardPass for the PocketPC.
Beware of the Turing Tar-pit in which everything is possible but nothing of interest is easy.
