There's a (small, but exploitable) segment of society that believes that their consumer choices reflect on their personal aesthetic; Steve Jobs has tapped into this as a source of profit. Aesthetic Value has always been a luxury: you always had to become a Prince before you could get paintings comissioned for the walls of your villa.
It's just a (small, but exploitable) differentiation: sure, I'm a drone, but ... oooh, shiny! They even self-refer in the ads: Look at me, I'm a Mac!
"whatever, dude"
