I'm not one to defend Apple when they pinch pennies by offering lower specs for the same price (RAM in all devices, SSD in Macs). But megapixels have been a bogus marketing number for well over a decade. The real test will be what Samsung's image processing can do with all that data - and I wouldn't be surprised if they do a pretty good job based on past years' comparisons. But it won't be because of the megapixels. That's just for marketing.
