I just finally upgraded from 9.04 to 9.10.
I had no problems. Im on a Gateway NX570S.
I really like the newer version apps like Inkscape.
Wireless works fine.
The only thing I can see is that its slower to start.
When it boots up, it goes to a black screen with a white
ubuntu symbol in the middle, then to another screen, then
you hear the little "enter your password" tone, and about 10 seconds
later you see where to put that password in. Other than that, cant
say anything negative at all about it.
