I have Windows 8, and I think the hate about it is overblown. It's nearly identical in functionality with Windows 7. The "Metro" thing is really not a big deal. When you hit the Windows button it pops up, and without clicking anything you can type to search for anything on your computer, it's actually pretty convenient. I never use the Windows "Apps", I just stick to regular programs.
Basically, I wouldn't let Windows 8 get in the way of your decision. For Windows laptops, I'd also check out Lenovo and MSi.
