Hi Friends, There have been many threads regarding screen protectors, and it does seem to make some sort of common-sense to use one for tablets and PDAs. But does anyone know how inherently resistant are tablet and PDA screens to scratches from using the stylus anyway? For example, it is physically impossible for a softer object (stylus tip plastic) to mar a harder object (tablet screen glass). That's why a simple test that would-be brides do to check their 1-ct rocks is to see if it can leave a scratch in a piece of glass ... (hopefully not their tablet screens!) So, has anyone had the experience of actually scratching up their tablet screen with normal use of their stylus? I've seen showroom tablet screens badly marred, but I have a hunch they were caused by (very stupid) people using a ball point pen on the screen or maybe using the sharper edge of the harder stylus casing, not the softer, white tip. I can also image a scratch can occur if a piece of sand (silicon) alighted onto the screen and it gets dragged on the screen when the stylus tip runs over it, thus scratching the surface. But barring such extraordinary events, can a tablet screen actually get scratched up by applying too much pressure with the stylus? David P.S. I can imagine one possible detriment of applying a screen-protector over a notebook screen ... it acts as a blanket over the screen, trapping in the heat that the screen is producing. I would imagine that amount of heat is very small, though.
