Well, I have three working computers (and three broken ones) so in
worst case I can always use one of the others while figuring out what
to do next.
Anyway, I just installed 12.04 and I have quite a lot of problems with
it already, but nothing worse than it's totally unusable, for instance
it seems like my own keyboard layout works sometimes and sometimes
not. Now is the "not" situation. No compose key, and the wrong layout
is being used. I guess that will result in a few new annoying threads
on this mailing list.
