Been using Ubuntu since version 7, but the recent Unity thing did it for me. Heard tons of great feedback about Mint so I just wiped Ubuntu and installed Mint. Pretty much already got everything I need configured and working, very little trouble at all. I still don't like Banshee though, and doubt I'll ever get used to it. I'll give it a few days though, see how I get on.
Right, now for my IDE and other Dev tools, and I'll be laughing. Love all the layout and menus, feels much more "normal".
