content: Not to the same degree as was once the case.  Biggest problem I have with Ubuntu and Unity is how they don't allow customization of the interface.  I just saw a story fly by (not April 1 related) that mentioned how Unity will now allow you to put the app tiles on the bottom of the screen.  As if that was some kind of amazing new feature.  I've been able to do that since I was running fvwm in the 90s.
