Surely this could be said about many other high-end fashion type brands. Expensive Nike trainers aren't worth what they sell for, most designer handbags are worth a fraction of what they sell for. These items also don't have any real technical merit to justify the price.
Fashion runs as a top-down economy. Most of the high-end designers are the ones driving innovation, and other designers/large corps soon imitate these styles a few years later for lower prices.
