I get the comparisons with a virgin product but the Watch was always going to be a hit. Its a wearable status symbol for some and for others a useful gadget. It fits in so many niches that it appeals to a wide base of customers. It also looks the business. Even the OG model still looks really nice as a fashion accessory. The lack of apps is never a problem because its not made for interactions lasting more than 10 seconds.
A headset is a different kettle of fish. It really needs to be almost launched as an accessory to the Mac Studio or Pro and aimed squarely at a niche industrial market rather than a wider consumer one where looking like a dork is second to using something new and shiny.
