7 is ok, don't get me wrong. But in the world of audio, XP is still the only Windows OS that still does everything that I need it to do.
The XP support is dying off so I'll be dragged into it and adapt, but that's the main hangup: XP was a switch I was happy to make. I'm still waiting on 7 to do everything I need. That's not all MS's fault though, its the 3rd parties too.
At home or a standard office desktop, I don't have any major issues with it.
