Recently I bought a PC laptop. I have windows XP at work and a mac at home. I installed ubuntu (the installation itself only took about 10 minutes as was the easiest installation I have ever done (of any operating system). The installation started just by running a small windows installer.
This was my first experience ever with windows Vista and whilst being impressed with ubuntu I was at the same time suprised at how horrible vista was. It was also dog slow so I thought I’d test test and the results showed windows Vista to be generally a 1/4 of the speed of the same machine running Ubuntu.
