I have played with consumer preview at my shop pretty much since it was released. Honestly, I do appreciate the fact that microsoft is trying to move forward from just putting a new face on basically the same old thing. Although, they basically just put a new face on the same on thing LOL. But since i have been playing with it, it hasn't given me any troubles. it seems to run nicely. I do like the new task manager simply for the fact that it shows disk usage, and i also like the microsoft office 07/10 options bar at the top of every explorer window, although i havent really needed it much, it is there incase the need ever arises. But my home machine, its keeping 7 ult. for a loooong time.
