I don't really see a reason to upgrade. The performance boost doesn't seem that big, I like Aero as it is, and I just don't see the need to upgrade from 7

Security reasons. There are more vulnerabilities to Win 7 that are known then there are known about Win 8.

I just don't like it,
It looks like it was designed for tablets and the kinect. It doesn't seem like a real OS to me.

Yeah, bad move on Microsoft's part. As I mentioned, there is Start8 (which I currently use).
