Not me. I'm still on 8.04 :/
So I have a dated vlc, a dated Amarok, etc.
I want to update, but I need to do a solid disk image backup of my laptop first in case shit happens.
I've been running 9.x or 10.x or so on my desktop, with Trinity KDE3, and have been pretty happy with it; hibernation started working after a somewhat recent kernel update. :)
I really like Amarok 1.4. Don't like 2.x. (Don't like KDE 4, either, so I'm glad Trinity is around, despite its quirks).
