> I found a lot of reactions to these products to be weirdly optimistic. Either I’m becoming more cynical with age and general tech fatigue, or certain people are easily impressed.

I think it's both. There's a loud cadre of Apple fans who will always fawn over whatever comes out of Cupertino, no matter what. That group shifts its membership over time, but they're always there, and they're, well, always loud. Maybe some of us have been a part of that group in the past, or at least perhaps looking at things with less of a critical eye than we do now. But it's normal to shift your attitudes on things, and normal for those rose-colored glasses to fog up after a while.
