You should use LTS (Long Term Support) versions of Ubuntu, 10.10 is not one of them and its end of life date is April, 2012 
Using very old Linux distributions in desktop computer is not suggessted. At the end of the day, you need to install newer version of a package which depends on newer versions of dozen packages. It is not easy to backport newer packages. So, you should upgrade more recent LTS versions. 
On the other hand, if your computer performance is too bad with newer distributions and you don't need new packages, security updates etc. you can continue to use an older distribution.
