I have to use Adobe Creative Suite for my job. By have to, I mean have to, because I get client files that are in proprietary formats, and my RIP software is only available for PC. It doesn't matter if I would prefer going back to XP, or even 3.1; that's simply not an option for me professionally.

Also, my work station doesn't belong to me, and you can be that if I changed the OS to a linux distribution I'd be looking for a new job pretty goddamn fast.
