The same could be said about the iPad and Apple Watch, no? Tablets and smart watches weren't popular before their introduction. With that said, I don't think the skepticism is unwarranted. Just because Apple has been successful in introducing new product categories in the past doesn't inherently mean that they will be this time.
As for the watch, watches are a very popular accessory generally, and there have been plenty of entrants before the apple watch, all the way from the casio calculator, to fitbits and pebbles to android wear.
If you were already into watches, and were already in the apple ecosystem, which I have to imagine was a large set of people, the apple watch was basically an insta-buy, not only because of its integration but also it’s customizability.
I don’t see those same variables present for VR as were for the watch, but I do see similarities between AVP and iPad in how it’s billed as a pro device, and I imagine it will suffer a similar fate of falling short of expectations.
Certainly how it worked at my company.
VR glasses have not yet gained mainstream acceptance among the general population in the way that phones had achieved before the iPhone. Practically nobody is saying that the Vision is a bad product, all of the skepticism is whether it’s a good product category.
