what cracks me up the most is my relatives who always buy a screen protector only to wear it off and it looks HORRIBLE with scratches (the screen protector) and a lot of bubbles or dust underneath, I am like why???? How does that not bother you when looking at the screen and also ... If it does not bother you, then why even bother with a screen protector. It wouldn't look half as bad after two years if you just used it "bare".
Basically they use a screen protector to protect their iPhone display from scratches but then use said iPhone with a horrible looking screen for 2 years. Only to replace it 2 years later anyway.
I DO use a screen protector because those fine scratches drive me nuts, even though I barely see them. Just knowing, that they are there, drives me nuts but unlike my family, I do get it replaced, once that happens
