It's a great point from a marketing perspective. Something users don't understand but can pretend too - I need this because it's got a f/1.8 camera, way better than the Samsung f/5.6 [I made that up]. What's super good is that it looks so technical, it looks like something that real cameras have about them too. Marketing fluff, yay.
Just like megapixels. The general public has this notion of "more megapixels is better". They don't understand that there's more to a camera than megapixels: F stops, low light performance, etc. I've actually met people who know 1080p "Full HD" is 1920x1080 but had no idea that it's only two megapixels.
