As I've said before, for the AVP, I don't think sales numbers really matter. It's getting to PMF. Now that the thing has been in-market for about 6 months, it's probably a good time to assess how that's going.
Has the AVP found PMF? No. - Obviously not, but that's fine, even the Apple Watch didn't find PMF until the second revision, and that was incredibly fast for any hardware product.
Is the AVP moving in the direction of finding PMF? I would say no as well. None of the directions they dangled in their initial release have had any meaningful traction, and certainly not enough to make product decisions for a v2. This is a really rough place to be in - I always talk about 2 of Apple's other pre-PMF products, the Apple Watch and the HomePod, and where the Apple Watch moved in the direction of finding PMF immediately, the HomePod did not, and to this day still hasn't, and thus has languished.
Is the AVP making moves to bend its product trajectory towards one that could find PMF? Yes, this is the second derivative, and no, I don't think so. At WWDC, Apple opened up some of its APIs to business/industrial cases, hoping that maybe they can open a new direction and find PMF in business scenarios, but this is speed running the Hololens playbook, which MS also did once they realized that all of their directions had failed. They tried targeting business/industrial first and found some traction there, like Airbus, but the market is niche/small. They landed on military in the end, which might work, but then they've so narrowly defined "Market", that no matter how lucrative it is, it won't really move the needle as a product category. As a consumer product company, I doubt this is the way Apple wants to go.
