You handled this question perfectly. Not even kidding. Down to every finer point of debate, you nailed the balance and gave the best, most helpful possible answers, including visual backup to express the true differences.
Absolutely fantastic. I'll be sharing this with other photographer friends and those interested in learning more. Great work. Thanks for posting.

My example comes from using a point-and-shoot pocket camera, not my phone. Very little control over shutter speed and aperture and such, but I've used it with great success for landscapes in good-to-low light. I've probably sold more prints from the P&S than my SLR, all because I had it in my pocket when the light was right.
