12mp doesn't stop me, APS-c doesn't stop me, lack of an LCD on the back doesn't stop me. What stops me is having to use the phone for an interface. Every phone app system I've used, back up camera on my motorhome, remote interface to my RV systems and a few others I can't remember off the top of what's left of my head have all been at best quirky and at worst non functional. Give us a standard interface directly to a computer and a more modern sensor and we might be able to talk.
