I like fluxbuntu better than xubuntu. It's not an official canonical distro, but i have a pretty old pc with only 64 mb of ram and fluxbox runs far better than xfce on it. I think xubuntu is a waste of time anyway, but i can't i8magine using gnome either, im kubuntu till death(mine, or theirs) Viva KDE.
Anyway, a friend of mine can get me a cheap mac(prices are unbearable outside of the us because of shipping and resellers adding up to the price) so I'm going to get pretty close to OS X and i know that its good, but like that guy i might choose to dual boot and have the OS X just there if i need it.
