The Mrs requires this (not "needs," "requires") for her business shots. When we're out documenting a new city or an event /ride for her website, she needs shots hitting Instagram in real time. There's a stream of fellow photographers doing the same, and online attention on the event now peaks during the event, not the next morning when everyone's gone home, downloaded and tweaked and sorted, and is now posting about it. Miss the stream, and it largely dries up. Catch the stream, and suddenly you get a flood of like-minded eyeballs who say "oh who's THIS posting good pictures of the event?" And they become followers. She's usually strongly pressuring me to just shoot with the iphone, for how much easier it is, so the wifi in the XT is all that saves me and allows me to shoot a "real" camera. Literally the first break we get, she says "ok gimme" and we throw pics from the cam to my phone, and off they go with hashtags.When I'm on assignment, I backup the morning's photos at lunch to my iPad via an SD card reader and then pick one or two to post online for family, friends, and readers. While serviceable, I can lose the dongle (done that before) and the process slows down when the card fills up. I've tried Eye-Fi cards and they've been notoriously unreliable.
For me, in 2015, I want WiFi or Bluetooth in my gear, as do other bloggers, photographers, and writers for whom being social and realtime are job requirements no nice-to-haves. This more important to me than an extra 4 megapickles or a FF sensor or an extra stop of low light performance/dynamic range. If that makes me a snapper, so be it.
