I've just read this entire thread... whew! I've come away with two thoughts:
First, I expect that no matter what happens to the industry (photo making tools, whether camera or phone), we will always end up with tools that do the job. Some of us get used to doing the job one way and hang on to that. Others jump from one tool to the next. But as has always been the case, successful use of the tool will depend on the brain/eye/talent, not on the tool.
And second, I now realize that I'm somewhat intrigued by the idea of accepting the challenge of doing my photography with a phone. Its tempting... selling off all this gear and live with an ever-ready phone! Hmmm....
