Having had several android phones, I can definitely say the gorilla glass 2 on my nexus 4 works and feels a LOT better than any other phone I've used regularly. (I don't like the slick back so much, have a rubber case for that reason)... I've only dropped it once (in a parking lot) and lucky it didn't break.
I have seen plenty of plastic phones break too. I'd rather have something that works better in my hand.
