How successful is the Apple Watch?

Earlier today, Quartz published a somewhat flimsy story about the modest success/relative failure of Apple Watch, without really any concrete evidence on why they think so. I totally understand they wanted to be skeptical, but it would have been good to back it all up with data. John Gruber in a worth-reading piece pointed out that “the nut of every “Apple Watch is a dud” story is the fact that it’s clearly not an iPhone-size business..But if Apple gets it into its head that they should only work on iPhone-sized opportunities, it would paralyze the company.”
