I've never been quite sure who the market is for a camera like this. Interchangeable lenses, but a severe lack of controls? Who goes to all the trouble of carrying a bag full of lenses, but doesn't want to make manual tweaks to their settings?
I've been in the market for a small mirrorless interchangeable lens camera for some time, to sit in my jacket pocket when I can't be bothered lugging my SLR around. But just because the body is small, it shouldn't mean any less flexibility than an SLR.
