So lets see, A pop up flash that bounces would add oooohhh let guess $35 to the manufacturing cost of the camera? Price the cameras in the class that typically have pop ups and their stable mates that don't.
So for perhaps $50/70 retail I would get a camera that has increased functionality for casual shooting. So small birthday parties for my grandkids, etc. and yet when I need the giant strobes, it doesn't get in the way and it tucks neatly away.
As power, no I don't need cavern filling power, as a previous poster mentioned this is for casual shooting.... a FF camera is not so much for a person who exclusively casually shoots. there is a difference. And of course this model can be upped a bit compared to the 3 meter models on most "casual shooting" cameras.
Combine it with the idea that it can be used as an optical trigger (not all of us have replaced our 2 dozen speedlights w/ radio controlled models) and in anything but a location shoot greater than about 75 meters, it works fine (actually did this w/ mT3i so pucker up buttercup).
It sounds like a damn fine bit of functionality to me.
