other observations:
Undervolting works!

(although it doesn't seem to be saving my settings between sessions)
As typical, installing is easier once you know what you're doing, but recognition of what needed to be installed (automatic detection of needed audio/video codecs, for instance) seems better than it was in Feisty as well, although that could be because I installed all of the needed codecs first in Feisty.
edit: also, links in Firefox open in tabs instead of new windows as they did in Feisty
overall, I'm pretty impressed so far!
