Upgraded my PC operating system to Ubuntu 7.10 (Gutsy Gibbon). The upgrade took about 6 hours because of the amount of (free) softwares installed on my computer.
The upgrade was smooth and went without a single hick-ups. I’ve written an Ubuntu Gutsy upgrade tutorial here
Compiz (read: cool desktop effects) is installed by default and it just take one-click enable it and it work well to on my 6 year old Pentium 4 1.7GHz pc. Though I think a leap to the latest AMD(or Intel Core 2 Duo) processor would be nice.
All in all, I love using Ubuntu, easy software installation, no constant virus/spyware problem, low maintenance and less headache, enough said.
