In my opinion, this was like going from 98SE to 2000. Windows 8 isn't liked due to its massive change in UI, but I liked the change, shows that Microsoft still has some balls, and isn't stuck in a rut.
I'll always run the latest version of software, because I like to know whats going on with my current version. I'm rather happy with the move from Windows 7, which is by far too "plain" for myself, to Windows 8. I'm very intrigued with it. I want to hack/mod the crap out of it. I think there are a lot of new features Microsoft should incorporate into their operating systems.
I firmly believe Microsoft needs to release a SPECIFIC version of Microsoft for a Techie/Geek Modder/UI Enthusiasts, simply so we can tweak the performance. But thats just my b*tchin' for the day
