I am buying them for the portability and power usage. They will eventually pay themselves off.

I can't run my 12x7950s at work (They create a lot of heat and noise.) I can however run 50 (planned) of these little suckers at work.

I could fill the whole 50 order in about 1 months time but I might as well kick things off and help others get small amounts as well. Instead of paying 1400 in power bills every quarter I can reduce and replace them with something right now. Something that ASICMiners have available and are shipping. I don't want to wait till September for this. The Diff at that point will be at around 98Mill (Rough Estimation). If I consistently add to the ASICMiner USB's which I might add take up a very small footprint. I can keep up with the diff changes. I've been calculating at a 20% diff rise - Adding these miners to my 12GH/s farm I already run and adding to this run with newer ASIC miners replacing the GPUs I will be able to keep ahead and make a profit.

If you have free energy who cares if it takes a year to pay itself off? Its all about multiples/quantity.

If you have 1 share with ASICMiner and you were paid .02 each week... it would still take you two years to have that share pay itself off. That's factoring in it does last that long and the share consistently pays it out with the ever increasing diff.


TL;DR: Why wait for empty ASIC (60+GH/s) promises when you can have something now factoring in no power. USB ASIC Miners are small, portable, silent and easy.
