Network hash rate increased ~ 600% in 4 months (from 25TH/s to 150TH/s) since ASICs started shipping...and the ramping up of ASIC production is just getting started...by many companies that haven't even begun shipping yet.  Expect a market flood.

I laugh at your 10% increase every month.  Do the math, and a little forecasting both optimistic and pessimistic, either way, the increase in ASIC hashing power will crush your returns faster than a Black Wednesday on the DOW.

Denial is a river in Egypt my friend.

I've been mining for 2 years now.  Made most of my BTC in the beginning when hashing power was within grasp of the common man.  I'd like to get into ASIC but I just can't justify the prices, especially if you have to pay in BTC.  I rather pay good old USD.

Just recently stop GPU mining.  I've reached my break even point on my GPU mining.  At current USD/BTC, it's just not worth it.  I'm willing to bet that a USB miner will no longer be worth mining in less than 6 months (1 BTC/device) from now and you will not recoup your 1 BTC you spent to get it.  I'll re-visit this post in 6 months and post an update.
