UB 9.10 has worked very nicely for me on my Thinkpads.
10.4 has three persistiant problems:
(1) Suspend to ram ( FN + F4 ) is totally crashed, must power down
to get back to operation.
Suspend to disk ( FN + F12 ) is fine.
(2) Trying to download anything larger than a long email disconnects
the wireless and it takes many tries to get it to reconnect.
Wired connection is fine.
(3) Frequent, random crashes with Firefox.
This is not in anyway a hardware problem, I can swap HDs between
two identical laptops and the problems will swap with the drives.
Once again, these are regressions.
FWIW, don't know if my Trackpoint will work after restore from STR,
it's  never made it back.
