It sounds like a lot of your opinions are formed within a very niche bubble.
Airpods for example - I see them everywhere, and every person I know that uses them, love them! Especially Airpods Pro 2.
iPad - I think the sales figures speak for themselves. It may not be popular among tech people, given they're used to a desktop environment, but I know many people that use iPads and love them.
Apple Watch, I admit is more of a mixed bag among the people I know and spoken to. But I'd say the majority like it, and have bought another one after their first one gave out/upgraded. Again, the sales figures speak for themselves.
The parent is living in a different reality. They are all hugely popular products, just because he doesn't like them doesn't make it not true. And their introduction made a massive impact. Maybe not on the level of the iPhone but pretty impressive. The vision pro thing is a major flop. Nobody wanted one before it came out and nobody wants or needs one now and it's too expensive. It's a shame, because like e readers they are massively underused as a technology.
Meanwhile I'm still here trying to make Shure happen. Their next bluetooth model will be amazing, I just know it!
