I don't know why people complain about Windows 8. I set my computer up in about half an hour and it was just as functional as Windows 7. I installed Classic Shell as a precaution but actually found myself using the start menu less. I don't use Metro very much mainly because the applications I use aren't in Metro so I have no need to visit it. Plus without a touch screen it's not as effective.
But I wouldn't describe it as horrible. Windows Blue with it's SkyDrive-pretending-to-be-iCloud with tight integration for backups etc looks quite good.
