As a pro, I'm running three Android and three iOS system tablets on my DJIs. In case one system stops working for some reason, I have the other to fall back on.
I use my iPhone and my Android device, and my iPad pretty much interchangeably, depending on my mood. My camera operator and VOs mainly use Macs so iPhones and Macbooks for them.
So far there's not been any problems with either system, and I've run several versions of both Android and iOS operating systems, DJI Go, Go4 and Litchi on all of them.
I think we had problems with cheap USB cables and plugs in the beginning, when we were setting up, but since we replaced those, we've not had more than the usual lags, glitches, etc., brought on by Lightbridge. I agree with Nate and the others, there's not much to call between them all these days, so personally I've been running everything (i1,
P4P, P3P) off my old Nexus 7, which I think is just the right size for me. Mavic is off my iPhone.
