I honestly don't see too much point using any form of protection. Why in the hell would you buy an $800 phone, then do everything you can to cover it up? Protect it, perhaps??? Maybe, but what's the point? Do you really think people are still walking around with their original iPhone in a protective case? Technology is worth less in the long run, so why not enjoy it and show it off when it's actually worth something, than save it and keep it in immaculate condition for when it's worth nothing???
Having said all that, I did recently break my SGS2 after 10 months of owning it....but my point still stands lol
(i was kinda happy it did break, because I had the perfect excuse to buy an iphone 5)
