2BTC for 300MH is still too much, even for the average geek who are not expected to be too deep into mining... 2BTC is 200 bucks for a tiny 300mh unit.
If it was 30 or 40 bucks for 300MH, then that would make more sense, for the casual user and those who want to really get into mining. I don't expect some random kid with a macbookpro to drop 200-300bucks for something like this.
I think there will be buyers even at that price in the very short term, just because of the novelty and the bleeding edge factor.
Anyhow, I still think this things with MASSIVE distribution at $40ish could be HUGE for Bitcoin. It would be spreading pills of monetary freedom, it could be a revolution.
That would be a revolution of sorts... it would be a company giving away money for free.
