Meanwhile, cached storage arrays (DMX, USP, etc.) have long hidden the slowness of disk drives by buffering writes, and this same technology also hides the inherent write slowness of raw (unbuffered) flash. There is no need to wait for PCM to have cost-effective solid-state storage - in the right platform and/or with the right drives, you can take advantage of the benefits of solid-state storage with today's NAND devices.
