Have you tried it? Because I did installed it at home since the public beta and it is not painful at all. Actually it is very reliable and fast. We can argue whether it would be successful or not but I can't see how it is painful.
I agree. I don't see any reasons why I would choose to use Windows 7 over Windows 8. Even if you don't use the Metro interface for anything besides launching apps, it is still a better OS.
