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.

I think you are the one that needs to learn math.

Profit from placing an order a year ago with BFL: BTC0
Profit from purchasing AM share at IPO: 3.4+.32 = BTC3.72 (ignores huge increase in BTC value)

0 < 3.72

Actually. Profit from placing an order for BFL 1 year ago is:

Cost: 149 USD
Hash rate: 4.5 Gh/s
Shipping: 2013/05/18
Delivery: 2013/05/25

Difficulties:
2013/05/25 - 2013/06/05 = 12,153,412
2013/06/05 - 2013/06/16 = 15,605,633
20313/06/16 - current = 19,507,041

Income:
2013/05/25 - 2013/06/05 = 0.1862 BTC per day * 11 days = 2.0482 BTC
2013/06/05 - 2013/06/16 = 0.1450 BTC per day * 11 days = 1.595 BTC
20313/06/16 - current = 0.1170 BTC per day * 8 days = 0.936 BTC
Total = 4.5792 BTC = 457.92 USD @ 100 USD/BTC

Electricity costs:
35W
0.2 USD per kWh
Daily cost = 0.35 * 24 * 0.2 = 0.168 USD
Total usage cost = 0.168 * 30 = 5.04 USD

Profit = 457.92 - 274 - 5.04 = 178.88 USD = 1.7888 BTC @ 100 USD/BTC

If you order from BFL now you risk that they will have their asses sued of them by everyone who ordered a Minirig. Which never shipped and the replacement product has 1/3 the hash power and is 3 times as expensive. I wouldn't pre-order from a company with such an uncertain future no matter how good their product is.
