What do people feel about the search and back button in WP

I seem to have a love/hate relationship with the back and search button in WP. I am not sure if its just me or is it my Lumia 920, but I hate the way the back or the search button are always in my way, always getting pressed and taking me somewhere that I don't want to go to! Especially when playing a game or watching a video (or even passing the phone to someone else), these buttons get pressed and start annoying. I just wish there were some way of disabling these buttons if required! Any comments or criticism?
