Thought about buying one for some time, but after reading of the OCZ HSDL ( http://www.theregister.co.uk/2010/09/30/ocz_hdsl/ ) i'll wait for the next generation hoping in bigger/faster disks, atm the size/price ratio is not yet good enough.
We're currently stuck with PCIe->SATA controller->SATA attached NAND controller devices that implement their own wear leveling and bad-block management with degree of effectiveness widely varying among manufacturer's implementations. We have to use post-hoc benchmark results to attempt to reverse-engineer the the performance/price/longevity tradeoffs that were baked into the device.
I suspect that no mass-market ASIC company will be willing to get this on the market until Microsoft ships an OS with a native NAND controller driver and flash-aware filesystem and a system OEM contracts with their BIOS vendor to allow booting from the thing.
Like many I've come to accept that SSD's will be roughly $2-3/GB for a while to come. I'd hate to spend all that time waiting while my spinny drive churns away valuable seconds of my workday.
