Obviously Canon was B.S.ing when they said they couldn't have both a pop up flash and wi-fi on the 6D.
I don't remember reading that. I read that the reason was because of the larger pentaprism needed for the full frame.
I could be wrong. Can you cite where Canon said that Wifi was the reason for no flash on the 6D?
I recall discussions to that effect at the time the 6D was released, but then again, it could just be my drug-addled child-of-the-sixties brain misremembering. Not a big deal anyway.
The point actually (and it was a small point in the entire post) was essentially the same as Neuro and Marsu: sometimes the "technical" reasons why a feature is not included turn out to be not so technical and have a lot more to do with market segmentation.
I do find it interesting that between wifi and GPS, they chose wifi. I'm indifferent to both, but I guess they had market research that showed the target audience wants to be able to instantly upload images or video to social media sites.
