I agree. Well, in a way, I think. It's pretty much your own fault if you don't decide to put a case around your phone and it gets damaged. Phones are worth a lot nowadays. Protect it like you would anything else you cared about.
I do think it'd be nice if phones were made indestructible, but that's not the case.
Would it kill them to NOT make the phone out of one of the least-durable materials on the planet, though?
I mean, seriously. There's a reason why things that are built to last are made out of materials like metal or hard plastic.
