Apple is for graphics artists for some reason. Microsoft is for newbies and non-power users, and Linux is for...what? Geeks? People who want to customise stuff?

I don't see an intrinsic performance superiority when comparing Linux to, say, Microsoft. In fact I've heard from users of both that Linux can't fold proteins as quickly as winXP. Hah.

But really, what 'purpose' does linux serve? It doesn't support a great deal of software, I wouldn't use it for graphics-intensive programs/rendering, and apparently it is inferior in folding proteins. I'm confused.
