Chip, the 9$ computer is here!
I've got mine in the mailbox one hour ago.
Now I've flashed it and it is running!
There is still a lot to do... the current image provided by Next Co. has very few user level tools. The gadget is powerful enough to run a (small) GNU-Linux distribution. (It has more memory than the first Raspberry PI.).
I can witness that the toy is real and works.
