I can't speak for everyone but I have a Windows 7 VM just for things like this. But I can say I don't think I've ever needed to use it. I run photoshop (cs5) in wine, although I could program get by with gimp I rarely do anything other than crop or rotate a photo. For Office I just use Google Docs or LibreOffice depending on the situation. I'd say 90% the former 10% the latter.
