I started as a dev and ended up in QA and liked it so much I never went back. My coding needs are met with automated tests, but I never have to fix anything in production in the middle of the night! All I have to do is break things during the day and send them back. :)
The best times were when I worked at an ISP and the devs were always convinced that I wouldn't find any bugs in their code. They lost that bet every time!
