At least give different distros a try in a VirtualBox, you'll think differently of Ubuntu in no time.I don't think it sucks, I happen to quite like it. Besides some of my University work is based on it, which is why there would be no point in me changing it.
I thought Ubuntu was the shit when I started using it, then moved on to the likes of Fedora and ArchLinux and eventually ended up with Scientific Linux. Fantastic no-nonsense distro.
