Does anyone here use non-Microsoft OSes on their primary computers?

I use primarily linux at home, and Mac OS X and linux at work. When I first started playing online poker for play money, finding a place to play was a challenge. Pokerroom.com runs directly in the browser, so I started there. When I decided to start playing real money, after I stumbled on this site, it became obvious that I'd have to get a windows machine up and running if I wanted to have more than one choice as to where I played.

I was just curious as to wether or not anyone else faced a similar situation, and where they are with it today.
