Surprised about Winamp and Songbird - I only run Songbird if I am doing little else, as it takes up about three times as much memory as Winamp does. Still think it needs a lot of work to become first-choice, but I have some definite fondness for it so far.

I'm curious about the text formatting toolbar. How useful have you found it? I've been trying to use HTML directly as much as I can over the past year.
