Why do you use OS X?

Hey guys,

Why do you use OS X? It's an interesting question, as I don't regularly hear from people on this site as to why they use OS X as their main OS. Please, I don't want any fanboy posts like: "wind0x sux LOLOL" or anything like that. I basically just want to know why you use a Mac with OS X and what you commonly use OS X for.

Thanks! :-)
