Is the screen protector really necessary for ipod touch 4G? i heard it's made with glass so the screen shouldn't get scratch easily right? I bought the case that cover the back of the ipod touch but i'm thinking to leave the screen alone.
ABSOLUTELY
I dropped mine the other day, and it now has a GASH across the screen.
I was doing a search because I am sick over it. I thought I heard that all these screens were super scratch resistant, and I drop it 2 feet on the bathroom floor and now its scared for life with a retina display.
I wouldn't get one. I have a dead iPod Touch that was given to me and I got my key and rubbed it on the screen a couple times ... no scratches. Historically, non of my iOS devices scratched, and that was the only time I TRIED scratching it, and nothing happened.
Sure they are cheap but they ruin the screen quality (its not as enjoyable). If you get the cheap ones on Amazon, you'll see a spectrum of colors when you shine light across it so if you do get one, consider the $15 dollar ones ... you get what you pay for.
