Fashion
After all the crap we've had to listen about how folks use iPhones just because they were fashionable. After years of this stuff even though the iPhones lasted for years and worked great, and then had resale value and got the Apps first, etc. etc. No said the media and the trolls, it is all because of fashion and looking cool, that was why the phones sold.
Guys, you haven't seen Apple do fashion and "Look at me I'm cool marketing." This is Apple doing fashion and looking cool. When these things are sold out across the world on launch weekend, then you can complain about fashion and looking cool being a driving force. When the Edition watch is priced at $3,000, completely sold out, and selling in China and the Middle East on the grey market for $10,000, that will be Apple doing fashion.
