Wifi is such a cheap feature to implement and it does not compromise wheathersealing or structural stability of a camera at all. those, who dont need it, can switch it off.
And it is not for the facebook / instagram crowd, since they will not bother lugging around a big old mirrorslapper. It is for those photograühers who have to shell out 300 bucks for cam ranger - simply because canon refuses to put a 5 dollar wifi chip + antenna into a 2012 camera for 3 grand.
Luckily its getting cheaper to make up for canons marketing differentiation ploys ...
Owner of a 6d and a 5d3 here. In regards to wifi ---when i got the 6d I thought the wifi was kind of neat. I used it here and there (via the remote app). It took taking selfies to a new level! that, and every once in a while, like on vacation or something I'd use the remote transfer app to upload something to facebook. LOL...other than that, I have barely used the wifi. It has stayed in the off mode for like 98% of the time I have had the body.
That sounds like what my use would have been also. Almost everything possible in my house is wifi and it makes life simple, but I don´t see how it would help me if I had it on a camera, unless it was so fast it made image transfer faster or if I was into very advanced remote control operations (which I´m not).
