Anyway, I know that there are millions of people who enjoy Ubuntu too. As they shipped millions of copies around the world previously (the ShipIt program), much people requested free copies and I think much people switched to Ubuntu. I personally think that it's the best operating system at all. I don't have used Mac but I've used Windows. Anyway, my experiences with Windows were bad. I like Linux than Windows. I think Linux has more advanced technologies (maybe at least for Ubuntu). It's features and possibilities are really awesome for me.
Anyway, let me describe more about this Ubuntu's new release. Ubuntu's newest version, released on day before yesterday (April 28), is so much different. It has a completely new user interface. The new Ubuntu release has lost it's 'Panel' feature (on the new interface, though you can select the classic user interface) which I think most old Linux users found useful. Anyway, switching to a new interface should happen someday that everything should be improved according to user's needs. Now, its notification area has some misses. I think, program icons that are displayed on the panel (tray icons) are no more available. I mean not the date and time, sound indicator or IBus button. But, some programs, when closed, aren't gone to the notification area. The missing of panel feature results in customization of shortcuts and some other useful features< like Main Menu or Menu bar, Force quit, and some other icons and features.
