Like the other unusual new "camera" of the week, the Samsung Gear smart watch, I will give some credit for trying to innovate, but in each case it seems a highly imperfect first attempt, that will likely only sell to gear-head early adopters. Maybe these efforts will help to develop more worthwhile successors. Not having even a choice of JPEG quality levels (let alone raw output) is a worry, though may be forced by WiFi bandwidth limits.
Not really an issue. The CamRanger allows control of a DSLR via wifi and you can shoot RAW with it. And review the images on your phone or tablet; albeit just the JPEG preview.
But anti-LCD composition traditionalists who forever perpetuate the myth of having to hold the camera at arms' length, instead of braced against one's eye socket where a camera belongs, should rejoice: you can mash these cameras against your forehead, or any other body part, or a wall, or a tree, while composing and tripping the shutter with your phone in the other hand!
I'm waiting for someone to fashion one up like a monocle and walk around sort of like a cyborg.
