That, and I'm getting a bit of the "if it ain't broke..." feeling...
Yeah that's kind of my feeling as well. It's already so fast I just can't imagine it providing a noticeable difference. "Improved power consumption" isn't particularly exciting for a desktop either. I don't think the SSD is the big power draw in a system with an overclocked 2500K and GTX460
It's not like graphics cards where you do see lower performance than you'd like sometimes, so drivers may improve it. I've never said to myself "I wish this SSD was faster".
