Years ago I would have agreed with you, now I'm not so sure.
Most users know so little about the UI of their computers that they don't know when to click the mouse once or twice.
They spend their day working on Windows, checkout Facebook on their iPhone on the way home, play a game on a Playstation then send some email using Gmail on Safari.
Then you have the major changes within operating systems over recent years, Windows Vista/7 and Windows 8 both introduced major UI changes as has OS/X.
Peoples interaction with computers has become much more diverse. Unless the UI is jarringly different they just aren't going to notice.
