True at the concept level - my first job in the computer industry was in the 1960s - but the specific circuit technologies used in today's laptop solid-state drives are very different and weren't around then. Their use in devices such as thumb drives and digital camera memory cards doesn't exercise them the same way as using them as a computer's main storage device does. While I'd personally be willing to gamble on one, the other view has some validity. The fact that solid-state disks using other technologies have been around for years doesn't, IMHO, change that.
