By that logic nobody should ever use anything besides Windows; they all have a learning curve for a current Windows XP/Vista/7 user. It's really not that difficult once you figure out about 3-4 new concepts.
Win8 is awful. While whatever they put under the user interface may be okay, I work with the UI so if it's an ugly, confusing collection of carnival barkers all screaming at me though their tiles, I'll pass.
Metro is very usable on a touch screen, especially for phone/tablet style apps. It's not really any worse than Android or iOS, but also not as elegant as webOS used to be before HP killed it off. It's rather out of place on a desktop PC though, and even worse on a server OS (what the heck were they thinking there!?). In my opinion their single stupidest UI decision was to have basically zero visual UI cues. If walking up to a Windows 8 system for the first time, a user would have no clue how to do something as seemingly simple as shut down the system. So yes, it's kind of annoying initially, but it takes only seconds to learn a couple gestures and a short adjustment period to get used to them and then you're fine. Or you can load a program to get the Windows 7 look.
I've been pleased (because the machines actually run a lot faster under Win7 than Win8).
Both personal experience and just about every test I've ever seen have shown Windows 8 performing as well or better (in a few cases, like boot time, a lot better) than Windows 7.
One exception I can think of might be if running Windows 7 with zero antivirus/security software loaded at all, versus Windows 8 with no add-on security software (since it basically has MS Security Essentials embedded in it by default and that can have some performance impact). That's not really a fair comparison though.
