I don't think atm that they're cost effective to act as a storage drive so I might be looking at a pair of the smallest ones setup in RAID 0 for my operating system.
As to when they'll lower their prices will probably match when more and more companies release them....
Quite odd (I stand to be corrected here) but I've heard nothing from the main hard drive manufacturers about solid state drives (e.g. WD, Seagate, Maxtor), only from Samsung who already make flash memory. Quite interesting really, it might be time for the RAM manufacturers to come out ontop e.g. I think OCZ have just released their own version.
