I find all the fuss to avoid scratches quite amusing. Nothing wrong with wanting to keep your stuffs as pristine as possible but some feels like an... obsession, that defies logic.
I laugh at friends who agonised over silver or gold iphone admiring its thinness when they finally make up their mind and get it, slapped a 2 inch thick purple barney suit over it for protection. I'm glad I've grown out of the "yay new phone now need front back top down & side protection" circus n just enjoy the phone in its original skin. But to each his own. It works for me coz I change new phone every 2 years and have enough common sense to avoid doing things that attract scratches, like trying to remove a speck on the screen with sandpaper.
