" still suspect that it's not a hoax as such, but it may be 'thin-air ware' i.e a proposed technology that simply isn't ready yet/capable of actually being created."
Lots of ideas can happen in Theory, Gordon E. Moore law says every 18 months the number of transistors doubles, which has been accurate, so double the fastest laptop cpu which is about 2ghz , i know some use p4 chips, which are not really good for a laptop, they overheat.
Anyway lets stick with 2ghz as the fastest now, 18 months time it could possibly be 4ghz then 18 months after that 8ghz, the technology has to be desighned and proberly tested.
