The fact that AM could half the price of those USB stick just proves how overpriced they were. They're still incredibly overpriced though when compared to BFL, and yes, I will compare AM to BFL because I'm a miner, not a retarded fanboy who worships companies and licks the arse of their bosses.
I guess miners like you like to wait a year+ to receive their orders, right?
Let's see, let's compare nothing to something, and then see which one is more valuable...
Of course not. Everyone wants their miners as soon as possible. I paid 1.6 BTC for a 5 GH/s BFL in April and I'll have it in August at the latest. 4 months != 1 year. Anyone ordering now will also have to wait about 3-4 months before they get their order.
Let's compare then smart arse.
AM
3.3 BTC per share
400,000 shares
0.03 BTC weekly dividend (extremely optimistic)
110 weeks = 770 days to recoup costs
5 Gh/s BFL
274 USD = 2.74 BTC @ 100 USD/BTC
0.018 BTC per day with network hash rate at 1000 Th/s, 153 days to recoup costs
0.0045 BTC per day with network hash rate at 4000 Th/s, 612 days to recoup costs
So, even if you did have to wait another year for your BFL miner to arrive, you'd still make far more profit from a BFL miner over an AM share. Face it, you need to go back to school and learn how to do basic maths.
