Installation went smoothly. The install quietly but firmly apportioned part of the disk to Ubuntu while Vista was asleep. Vista took the hump about the reduction in its disk space when it woke up. It went skulking into the corner doing a chkdsk or something. Anyway, it all "just worked".
By "all" I mean the usual "all". I.e. all the stuff you really, really need like networking and e-mail and all that.
Some tweaking has been ongoing - especially to enable the pen stuff. So far nothing major to report.
Compiz fusion doesn't like the graphics card but its possible to tell it to fly dangerously and then its mostly fine. Useful for moments of Mac envy.
On the "bummer" side, emacs has some stability issues related to Gnome by the looks of it. Xemacs to the rescue there.
Pidgin occasionally has a hissy fit so I'm trying Kopete.
