I have always used thin film screen protectors (Invisible Shield for example) on my mobile devices... cell phones, MP3 players, Game Boy, etc. Even though I am very careful with all my devices, it gives me piece of mind to know that if my screen does somehow get knicked or scratched, all I have to do is peel the protector off and apply a new one. Does anyone plan to use a screen protector on their Pandora? If so, what are you planning to use?
