The wide perception of Butterfly Lab's ASIC solution as being a scam has resulted in wide interest in alternatives, which are legitimized by seemingly functional and deliverable ASIC solutions by companies like Avalon. At over 6,000 Mh/S per module, they exceed the best GPU/FPGA solutions for mining almost by a almost a hundred fold (after factoring power consumption), which has produced a tangible market of bitcoin hardware.
Regardless of whether specialized Bitcoin ASIC hardware is cost effective, the production serves to legitimize the currency/producing market as a whole (as well as reinforcing the hype/gold rush mentality for miners and speculators).
I'm still not sure how/whether the currency will eventually settle, but it is very interesting to follow.
