What is the difference (aesthetically) between having a scratch-less screen with a cover that makes it look scratched or having a naked screen with a micro scratch? Plus, because the screen protectors scratch just looking at them, your device will always look scratched. Is there a point in spending 20min and $12 every month or two to have a false sense of security? I mean, just because you have a screen protector, are you gonna be less careful with it?
I think one of the big points missed is resale value. One of the main reasons I use a case and screen protector on my devices is because when I decide I want to upgrade, I can sell it at a much better price with it in pristine condition. Because of this, I'm able to upgrade to newer devices frequently for a very very small price. Plus, I don't think its a false sense of security. I've dropped my phone before and scratched the screen protector, then just swapped it out for one of the other protectors that came in the pack. Now my phone still works and still looks pristine. Its not like if I drop it and scratch the screen I can just swap it out for a brand new nexus screen.
