I use both Linux and Windows (Linux professionally, windows personally)

Got a buddy of mine that will wax on for hours about how windows is pointless and should have been replaced by Linux years ago. I'll then go "Cool, so uh, did that game download yet? Lets play!" Then start up the game. Four hours later and he's still trying to get the sound to work or make the graphics display while continuing his rant on how user friendly Linux is.

Like, Linux is great and all, but fuck me, it's not user friendly.
