A free update, weighing in at 190 MB!!! OS 7 was probably only about 8 MB total and I think a few floppies of that was fonts! (Or am I thinking 6.0.5?)
I’m hoping for better Airport connectivity and some more reliability with Mail and faster sync with MobileMe. Better security and a Trackpad System Preference Panel for the MacBooks too. More info here.
A reboot before installing might be a good idea… Backing up too, but that’s not likely to happen…
