is there much difference between them, im on a dongle so i wanted to know if i should waste my usage on an update.
Not really … except you’ll be forced onto Gnome3 and/or Unity … your only real issue is that 10.10 won’t be supported after April 2012
… and you can use a “fallback” to Classic View without effects and get a wonderful, intuitive appearance.
Mark suggested I use the command: “sudo apt-get install gnome-session-fallback” to get it.
It adds another option to the available appearances that can be chosen at login.
