"mobe-makers sometimes resort to less-capable cameras"
Sorry, but I don't think that pixel count defines camera capability.
I have a Canon EOS 400D. I have 3 different lenses I can put on it, 2 rechargeable batteries and two SD cards that, put together, can record a total of over 700 high-definition pictures.
There is no smartphone that can hold a candle to the picture quality of that camera, even if it only has 10MP.
The only issue is that I can't carry it in my shirt pocket.
