I've only read about the solid state drive in which the chief advantage seems to be durability, with only a few applications benefiting from a somewhat lower power consumption, and the major drawbacks currently being half the memory capacity at a 50% increase in cost making it impractical for most consumers at this time.

Are the other new technologies any better poised to see widespread application?
