Re: sticky out camera on the iPhone6
Maybe. At least it gives you some tactile feedback so you don't obscure the lens with your finger when you take a picture. True, it does protrude, and therefore might cause an issue when putting it your pocket. Perhaps.
You could say exactly the same of a phone with big raised volume buttons - "Great!" you think, if you live in cold climes and regularly wear gloves. "Nasty!" you think, as the phone's buttons snag on the pockets of your linen trousers on the way to the beach.
Product Design, like Engineering, is often about making decisions - compromise is inevitable.
