I think this idea has potential. Paired with a high res tablet mounted on a tripod, it might be very good for landscape (or anything still) type shots. I have a little (very little) experience with a 4x5 view camera, there is something to be said for composing the image with 2 eyes. Since tablets are getting such good displays these days, it could be an interesting experience to frame a shot looking at a 300+ PPI display, maybe being able to adjust the light balance, etc. while looking at such a display. Or compose in black and white.
The challenge will be battery life, especially on the phone/tablet. In addition to managing your screen settings (i.e., power conservation setting might not be conductive to composing/framing or evaluating exposure), the constant-on of WiFi from lens to device could result in a big drain.
I'm also interested in the a) ergonomics and b) how they plan to integrate with non-Sony phones - the product shots are conspicuously homogenous in terms of brand.
Edited to add: this makes having a phone with a LOT of storage key, assuming you can write to removable storage using the lens (is it fast enough). Otherwise native RAM capacity becomes a premium. Right now, it's still deathly expensive to get 64GB phones.

If that's your main goal, consider the CamRanger to use with your Nikon gear. You can not only compose and review on the big screen of an iPad or similar, but totally control your camera remotely, too!
Yeah, I've recently discovered there are many options to tether a tablet with a "regular" camera so I will be exploring that. I'm going to start with a less expensive, wired tether, and if I like this style I might get the CamRanger.
