Going Ubuntu

I can not stand Vista anymore. I am a proud owner of a Thinkpad T61, but after 3 months I noticed that things are just getting worse. Vista has lots of bugs, crashes a lot and it is painfully slow.
This week, Vinícius, a geek student of mine, convinced me to try Ubuntu. I downloaded the iso file, burned a CD-ROM and ran it. Everything went surprisingly smooth. In minutes, without any configuration, the notebook was wireless connected and running Firefox faster than ever. I tried OpenOffice and it opened a huge doc file with track changes without any problem.
So, this week-end I am going Ubuntu. In order to prepare for this historical moment, I have printed the instructions and I've downloaded the episodes of Going Linux podcast. This show is co-hosted by Serge Rey, the über economic geographer. (Update: I've just noticed that Serge has his own podcast on Linux installation!)
Any suggestion or advice?
