Screen protectors are an unnecessary item which serve only to degrade the view of the screen. Screen protectors have been marketed for well over a decade going back to the PDA era. But to my knowledge, most screens have been too resilient to need them, and the Sony Readers are definitely in no need of them. If someone presses hard enough to scratch an eInk screen, then they are not using the screen properly or they are using a sharp-pointed stylus. Either way, it is user stupidity and not the quality of the screen that could be called into question. I would save my money and leave the screen as it is.
