It depends, I have one, they're nice to have if you want to check to see if you got the shot you wanted, but they do add some weight to the gopro, and drain the battery if you film with it on. Also, it is a bit confusing at first to get to and from the play screen. If you're using your gopro primarily for skiing and want to film then watch what you filmed on the lift then it's good, otherwise, there's not too much point for it.
