it goes everywhere with me, so i've been walking around with the n770 in one pocket or another without its cover basically since i got it (early adopter) and there are no scratches, dents or dings on the screen. the rest of it is unmarked as well. in addition to the stylus have used pens, pencils, small phillips-head screwdrivers, sticks, fingertips, fingernails; looks same as new. in the winter i wipe it down once in a while to get the hand lotion residue off. or spaghetti sauce.
