Whaattt?!?!?! That thing looks rad!!!!!! I don't know why I am not sending you BTC right now!!!!
It's pretty cool, especially if you do a lot of on-the-go computing. The USB receiver is one of those micro-size units, so you can just leave it plugged in, and the Cube itself drops into your pocket.
Anyway, I updated the OP to reflect that I'll take NMC, LTC, or SC as well.
