I have upgraded to Feisty on the used laptop I bought. I started with
Edgy a few months ago. My only issue was burning a CD with no MD5 errors. Every single one had a single error on the same file. I gave up and loaded from it anyway and it worked fine.
My only real issue was with restricted drivers. The installation loaded an NVIDIA driver, but did not activate it. This gave me crappy performance on games until I went to the Restricted Drivers option and turned it on.
Definitely download the graphical NDIS wrapper utility if you are going to install a WI-FI card. It makes the process much easier.
Linux runs very well on an old laptop that would probably choke on XP and run screaming from Vista.
Favorite Linux Game: Angry Drunken Dwarves
