Practical Cheap Solid State PCs

With the announcement of SDXC at this years Consumer Electronic Show in Las Vegas it leave me wondering how long it will be before we see reasonable priced terabyte Solid State Drives (SSD) in PCs. Current SSD are expensive for 60GB or 120GB drive. SDXC promises SD cards of up to 2 terabytes that should be enough storage for most PC users needs for a few years at least.
