I'm running Windows 8 on one of my notebooks, and I don't know if people are going to like the new "Metro UI" which replaces Aero. This might be a hit on tablets, but a big fail on desktops and notebooks.
Yea, from what I have seen of Metro UI, I have zero interest. I feel like I just got Windows 7 (even though I have had it for years), and I am very happy with it.
