I recently had to buy a Mac to write an iPhone app for a project. Despite how "user friendly" they are supposed to be, I find it very difficult to use, because I haven't been using it for years. Every time I need to do something I find myself hovering over every (unintuitive) icon hoping the tooltip will be the one I'm looking for.
I have only used Win8 for about an hour, btu I found myself doing the same thing -- hovering the mouse and clicking on random things, hoping they would do what I wanted. Finding the desktop screen, finding my way back to the Start screen, and figuring out how to shut down/restart each took me several minutes. That doesn't necessarily mean it's bad, it means they need to make it easier for people to migrate who are used to what is essentially the Win95 interface.
