They certainly aren't, but I still think Apple have failed by not having more megapixels, simply because 90% of the Iphone buying population have no idea "why megapixels aren't the end-all-be-all for image quality". They think the more megapixels the better and that's potentially a big chunk of buyers that could be swayed elsewhere e.g the Z1.
So you are saying that Apple should produce a rubbish camera because 90% of people think it is better, instead of a quality camera?

Alternatively, they chose profit margins over quality or quantity.
That's nonsense. The sensor size is what costs money, and the sensor size has increased. Dual LED flash costs money. Better lens costs money. Megapixels don't cost anything. Except quality

Not the most predominant factor unless you are printing poster size photos... It still matters though.
In that case the noise added by having more pixels will become even more visible.
