I don't want to give you the wrong idea, I don't think the s4 is a giant pos. I don't care about breakability when deciding on a phone these days.
I only am bringing this up because people (like kolyan2k ) the are going around saying the opposite. It rubs me the wrong way.
Just because S4 slided more that S3 doesnt really mean anything (never had a phone slide since 1st iPhone lol). Its pretty much a fact that S4 has more chances surviving a fall without a single scratch vs glass or aluminum phone (especially if its made with many pieces glues together (aka One))
I've had iPhones, bunch of HTCs, Galaxy S, Galaxy Nexus, and now N4, with out even a question Galaxy S and Gnex were bullet proof compared to others.
And I do care about breakability, its a phone that I carry with me every single day, accidents happen.....and I hate buying a thin phone and wrap it with bulky case. This is where s-view and flip covers come in too....I think its a pretty cool invention
