The concept is ridiculous. People are abandoning point and shoot cameras because of the convenience of using their phones...something already have with them. Adding this large, cumbersome camera into the mix is actually more complicated than simply carrying a thin, light Sony RX100. I truly don't get this at all.
This won't fit in your pocket on its own or while mounted to your phone. So, the steps to use are, 1) take out of purse/backpack whatever, 2) dock and attach to phone, 3) take picture, 4) put away? That is a worse solution than either just using your phone or pulling a point and shoot of your pocket.
It also looks incredibly awkward to hold when not mounted to the camera. People are going to be dropping and breaking these like crazy while try to mount them to their phones.
