Yeah, but a 2GB flash drive is what, $20.
@$10 a gig that’s $2500 for a 250 GB flash drive that could replace your magnetic platter HD.
I know the formula for cost wouldn’t be that simple, but basically flash memory prices have to come WAY down before they’ll replace a real HD.
I can see having your OS and real critical apps loaded in flash memory in the near future though.
