Do we still get fooled by Megapixels?

Anyone who follows technology to a reasonable extent knows that specs and numbers on a sheet (about a product) means nothing and this is even more so valid for Apple, a company whose products play so well between its own hardware and software. Apple often trounces rivals that boast better specs (numerically), in actual real world performance and more often than not by a huge margin. Same story here from the WSJ on how the iPhone 6's camera trounces Samsung Galaxy S5's in real world performance, though the Samsung phone has twice the number of mega pixels as the iPhone 6. 

Apple arch-rival Samsung includes a 16-megapixel camera in its Galaxy S5 phone. The main camera on the latest upgrades to the iPhone line still has just 8 megapixels. Yet the images from both the iPhone 6 and 6 Plus are the best I’ve tested on a phone to date.
