I'm still dual booting Windows 8 and Windows Vista. I had Windows 7 on my previous PC and liked that as well, but I honestly don't have and have never had a problem using Vista.
Windows 8 is interesting for sure. I like it a lot but it's definitely a different experience. I do like the concept of being able to do all your "casual" computing tasks from one place, while still having the ability to run heavier duty programs just like any other version of Windows.
