The thing I dont get is why camera manufacturers dont learn from camera - phones.
Think of a DSLR with built in Operating system that supports 4G / Wi-Fi / 500px / Instagram / snapchat / facebook etc.
Why not??
I'm not entirely certain I'd want such features in a camera. If you have a smartphone, you can take the photo, edit the photo, and then post the photo. But if you have a camera and you're serious about the quality of your photos (and if you have a DSLR there's a good chance you are) then you probably want to tweak the image before sharing it rather than have the camera just upload it "as is".
So you could add photo editing apps to the camera... but this reminds me of the time when car manufacturers realized people wanted phones in their cars... so they started offering integrated cellphones for the cars. The "problem" was the manufacturer just offered you ONE phone model. Mobile phones are like fashion... people don't want to be told what one thing to wear, they want to pick it out based on their own needs & taste. The same would be true of image editing apps... I don't want a manufacturer thrusting their idea of an image editing app on me and telling me that if I use their camera then I have to use their app because it's all integrated to shoot, edit, and post.
What I really want is something that will let me "shoot", and easily transfer the image to a device of my choosing... edit it there (and honestly... I am NOT going to edit photos a 3" screen on the back of a camera), and then upload it to possibly multiple locations.
I really like Apple's model in that I can add information (such as a photo) from any device and within moments it shows up on every other device.
But there is a catch... most carriers don't truly allow unlimited and unimpeded data volume. Even "unlimited" plans tend to hit the brakes and slow down your data speeds after you exceed some threshold (even if they don't charge you more) and most plans still are not unlimited and have overage charges. That means when I'm "out" shooting, I really don't want the camera to just start syncing everything. I'd rather wait for it to be on a WiFi connection to do that.
Apple does have a slick protocol build into their devices that allows two devices that are both trusted to auto-detect each other via Bluetooth (bluetooth is very low power, but also very slow) and then use Bluetooth to negotiate a peer-to-peer WiFi connection which can then do a high-speed transfer. That way you don't have to leave the WiFi connect all the time (wasting power) but it's painless to establish. Usually it "just works". Now THAT would be something I'd be interested in because most WiFi cameras are still cumbersome to use when it comes to establishing the WiFi connection.
Keeping with openness (something most camera makers are definitely NOT good at doing)... it'd be great if the camera was an IoT device with published REST-based APIs so that it wouldn't really matter what "other" apps you want to use... anybody could code against the published API.
