Ive used this Distro.. for little over a year. Never really had problems with it, until now.
I switched to Linux, because Windows was moving in the wrong direction with their operating systems.
Ubuntu was PERFECT, until 11.04 (the latest release) mainly because of the Unity Desktop.
yes i realize that you can go back to gnome 2 very easily, but, i don't wanna have to sit here, with Gnome 2, and know that Gnome 3 is out, and running very well on other distributions of Linux.
But other than all that, Ubuntu is the easiest Linux OS I've used.
