i dont know maybe theyll come out with a 2.5 then... after all they do have alot of the old cases and board around hell id take 2 2.5s if i didnt have to wait XD
Bearing in mind the original Jalapeno was to be 4.5 GH/s running on under 5W USB power without additional cooling, at the current specs to run on less than 5W means it wouldn't run at more than 1 GH/s. Even the best estimate for the chips at 3W per GH/s doesn't give much more than 1.5 GH/s, but there are additional components required for it to even work.
Even so, on that basis they could easily compete with the 300 MH/s USB devices from ASICMiner. If they can do a 1 GH/s USB powered miner for under $150 I've no doubt it'd sell pretty well.
