So I finally checked to see if I could upgrade to 12.04.1 through the update manager and it's there saying I can upgrade. I already upgraded from 8.04 to 10.04 so I'm thinking about going to 12.04. This is, my PC is pretty old. It has about 600MB or RAM so would that be enough?

I had a PC that had about 2GB of RAM, but it died. Funny how newer PC's seem to crap out more than the old ones.

Anyways I was wondering if I should upgrade or not?

I heard someone on here say it's best to go with Xubuntu for computers with ram less than 1gb. How would I upgrade from Ubuntu 10.04 to that though, if it's even possible?
