Never heard of it. I must be out of touch.

Neither had I. I don't like how they try to jam just about everything into the same program.

On the flip side, I'm tired of adding plug-ins and Greasemonkey scripts to Firefox, just to get it to do things that come built-in with Opera.

Yeah, but that's still browser stuff.
