Thanks for the advice guys. I'm thinking though that maybe I should just
stick with 8.10 for a little while longer seeing as 10.04 is soon to be
released. I have a laptop I could try 9.10 out on if I want to, so I guess
I'll still get to try it out that way. Was hoping I could just upgrade with
the disc though. Haha... Guess not.

Tell me though if I run the 9.04 upgrade through the update manager will my
current installation still work (ie my tablet etc)? And what size download
would I be looking at?
