Most creative pro apps are only available on Windows or OSX. I don't hate Windows7 but I find OSX superior (integration, stability, decent shell etc). If you want OSX, you generally need a Mac.
I'd switch to Linux if the apps were there, but it's not even close. And I'm an edge case, I suspect most creative types would rather not mess with xorg.conf.
That's why I wish, over and over, for a Wine equivalent that runs OSX apps.
I have ran some windows audio applications on Ubuntu 10.04 and the timing accuracy (tested by specialist software) was several orders of magnitude higher. In addition, I can achieve higher workloads. This is all with software that wasn't even compiled for my OS.
