scratch RESISTANT. glass can easily resist sharp metal objects easily. but theres always one thing glass will lose to. a grain of sand

put on grain of sand on your finger, or your spen, swipe on screen, GG

one nice large scratch u can dig your nails into. so get a glass sp (its nicer to swipe and not as much as an oil magnet than plastic, and more resistant to scratches than plastic too) over your glass

no intention of scaring u. speaking from experience and facts. i used my devices with gorrila glass and even those diamond glass on my watches. go to the beach and BOOM scratches.

it doesnt take much. u play with sand didnt wash hands properly swipe screen got grain of sand, BOOM scratch.

drop your spen on the ground, collected a piece of sand on the tip, didnt clean, swipe screen, BOOM scratch.

get glass. because plastic hardness is usually around 4-5H. While glass is typically 9H. (i think, not sure about rating but definitely harder). And finally glass can never beat those natural minerals u may find on the tarmac road etc.

yeap totally.

as long as users are aware that their screen is not scratch "proof". I totally get the appeal of using the phone raw (no case no SP) as well.
