I've seen some guys do that, but man, what a nightmare to review. I've had an inspection that lasted a full eight hours with something like 28 structures before. No way it'd be reasonable to listen to that over and over to get the info I need. Voice to text picture captioning would be amazing though. As well as the ability to draw on screen on real time. Drawing on screen is one thing I miss about using a tablet, but probably the ONLY thing. An actual digital camera takes much better, and faster pictures than any cell phone/tablet.
