In fairness, any stuff you don't wish to use doesn't get in the way. I'm a longtime Opera user (I bought a license back when it wasn't free yet!) and I don't use the built in Mail and RSS clients. They don't get in the way and it's still extremely fast. I did switch to Chrome for a while as the Mac and Linux versions were rather unstable in the early 10.x series, but 10.6 is solid again.
