Skeuomorphism goes in the other extreme direction though. One doesn't need flat design or skeuomorphism. There's a nice balance of UI elements that sit in the middle. I think Windows 7 was probably a good example of just straight up boring buttons and controls.
I hate it too. I understand what people had against it though because Apple (led by Scott Forstall) took it wayyyy too far at one point. The notepad, the game center, it was a joke. It became its own objective.
I think the current bland flatness is a kneejerk reaction to that (kicked off by Jony Ive who was probably angered by Forstall's design).
