The only thing that I still can't get my head around is Gnome 3's message and notification tray. Gnome 3.0 was released in Oct 2011 and software developers have showed no interest in Gnome's message tray. Most software still don't support or even care about it. In spite of this reality Gnome developers have refused to make any changes to their ideology of system icons and notification. TopIcon extension that puts system tray back to where it belonged has made Gnome useful for me.
