I would hate to be a smartphone engineer. Think about it.
You've got to make a phone that's thin and sexy to appeal to the public, but has to fit all of the electronics in it. The thinner an item is, the easier it is to bend. You could add support here and there, but this adds weight and takes up space necessary for its various components.
You put it all together and test it to see that it won't bend with W number of pounds on pressed against its XYZ midpoint. Is that enough? No because the boss wants it to be even stronger? Ok let's make it stronger. Ooops! Too thick! Lets use a different materials. Whoops! Too heavy - the sales team pissed pissed now.
Try this other new Material. Great! Pretty bend proof now but Hey! The signal waveform is all messed up. Let's go back to material ABC. Dammit! ABC is in short supply / too expensive / causes allergic reactions / is made from dead fetuses. Whatever.
Sorry KillerK OP : There is nothing "fail" about the iPhone 6 as you posted.
According to Forbes, Apple sold over 10 Million units in the first 3 days of its release.. There is nothing fail about that.
Peace.
