I have ordered this so i can get my big scope out of the studio and use it for electronics, it costs not much more than software anyways and could be handy especially if you tinker with audio electronics.
I will post my impressions.
Basically they took an mp3 player and changed the firmware and connections
well done China 
they have a deal going that if you buy one and post about it on a blog they will give you $100 credit, which is more than it costs, however if you dont mess with electronics a credit at seeedstudio aint worth much
