Get Windows 7 and leave it at that.
I want to love Linux, I've tried to make it usable many times over, but it's just so user un-friendly. It's gotten better over the years with package managers, but anytime you go for help with an issue it's all command line (not a big deal, it's just words it's not scary) and essentially nonsensical packages that there is no way you'd be able to ever figure out on your own.
On top of that, media playback is a pain to get set up since a lot of distributions don't include things like MP3 support and require you to get them yourself, often after mucking through admin menus to enable 'non-free' (as in not open, not you pay for them) packages.
