I’ve just upgraded to the new Ubuntu version, and I have to say I’m thrilled so far. It has fixed many of my earlier problems. For instance, it’s much more responsive than before, because the new Intel graphics driver is so much better. Before I couldn’t play most 3D games, but now I can. I can even use Compiz! And everything feels much snappier because it has removed delays when hovering buttons opening menus, switching windows and even just opening tabs! The user interface has undergone a graphical overhaul which I find really pleasing with new icons and themes, new login screen etc. And finally the forward and back mouse buttons work in the nautilus file browser without doing anything
