Like most of the reviews I’ve read, Jakob Nielsen thinks Windows 8 sucks. I don’t agree with all his points, but he makes some solid points against the user interface of 8.
Then again, he also concludes his review saying he’s a fan of the ribbon in Office.
You should have kept that last part to yourself, Jakob.
Update: I also love how he has to qualify his review by saying he doesn’t hate Microsoft and he’s not an Apple fan boy. Like it’s impossible to be a Microsoft user but not be a fan of Windows 8.
