let's be honest honest. maybe YOU have to buy a case for every phone, but i think it's safe to say a ton of people don't. i don't think anyone is saying that plastic is better than GG. my thoughts are similar to bnice in that clearly apple is showcasing the design of the back of the phone being glass....nothing wrong with that if as bnice said it's for looks or whatever...but IMO it does kinda beg the question of if you're gonna make a phone with a glass back, why make a stock cover for it that hides it's shiny splendor, and ultimately leaves you with a ... rubber...back....why not make a cover that goes only around the edges or something, so as to always be able to show off that shiny glass back, especially since it's being treated as such a magnificent piece of handiwork...i myself think it LOOKs very sexy, but the practicality of it leaves me wondering...great marketing move to me as well to make the cases for it right off the bat and advertise them right alongside the primary product...(i've never seen that done before where a case for a phone shares the spotlight with said phone)...good luck to those with sweaty hands who own a glass phone...just sayin...
