LOL...they are Tesla fans! Which by definition are people who going to be early adopter types.
What made other Apple products special is the broad appeal to consumers. You could pull together 38 owners of Honda, Chevy's, Nissan's, Lexus's, BMW's, Hyundai's, Ford's, Kia's of any age group and likely 40% of them have an iPhone or iPad.
But the AW at it's current price/functionality is a niche product.
Yes Tesla owners are early adopters but not necessarily geeks. Another interesting thing was that almost half of the AW's were being worn by women.
By definition, AW only sells to owners of iPhones so sales should be much smaller than iPhone sales. I expect AW will make several billion dollars this year. I would love to have a business that size.
