The Oly specs are not too shabby...better than a camera phone....probably not as good as a stand alone M43, DX or FF body. What's the market for these things? People who want the ultimate camera accessory for their iPhone?
The Oly AirO1 looks better IMHO than the DxO. It works without the connector issue (although be interesting to see if the viewfinder is faster with the DxO; doubt it) and it's cheaper even with a lens, although you gotta factor in lens quality. But it's huge, for us, that it can use any M43 lens or an adapted lens (and there are bazillions of those). Then sensor is basically the same as the E-M5, which is very good. No stabilization though.
It does seem an odd market. I love shooting macro and remotely (at least somewhat remote; can't go too far) with a wifi M43. I've seen the Air01 mounted at the end of a long tele on a tripod with a tablet mounted alongside as the viewfinder; very cool. And it would be nice for tethered shooting. I would think any of these would kinda stink for action shooting, both because of an EVF and the ergonomics. Especially the Air01 with a bigger lens. Unless you've got a camera sitting unmanned behind the goal operated remotely.
But those are all functions that an existing DSLR/M43 user would like. I just don't see that a smartphone user is gonna want to bother, especially since there are some killer ILC small cameras, or even P&S small cameras, that cost less and can work alone.
I think that what has to happen is a killer hardware feature (super small tele, drone-ish very remote control, Go Pro like video, weatherproofing, etc) combined with some killer apps (Lightroom-like organization within the smartphone with focus stacking, incredible time lapses, motion activation, and bunches of stuff we only do on desktops now, plus what we haven't thought of).
Maybe just a SIM slot in your camera...they do it cars, why not cameras? $10/mo for unlimited uploads via cell of all photos and messaging.
