In my main camera use case the "gopro" form factor has much better ergonomics than a phone, by a wide margin. Unfortunately, that market is wildly underserved because all existing cameras in that form factor barely consider stills even an afterthought, if they consider it at all. I'd pay real money for a camera that is on par with phones but does not come with an almost face-sized TV attached.

(I use an RX-0, which at first glance seems to fit that bill, but doesn't really: it's an extremely small movie camera that only pretends to be a very small compact for addressing a wider audience than it deserves)
