The metro UI was a forced major interface change that was terrible experience on Windows (8). It was put in place to bootstrap a mobile app ecosystem for Windows Phone at the expense of Widows (desktop) users.
What #Apple is doing is more benign, mostly altering the appearance in a fairly minor way (afaik). However, they are doing it so that apps designed for #iOS and #macOS default to being compatible with #visionOS with little to no extra effort by app developers. That is, bootstrapping the ecosystem on that platform. That’s the similarity to Metro.
The question is how much of a setback in usability and appearance will this be for iOS and macOS users for the benefit of this goal. We’ve already seen a big regression in Mac apps for iOS convergence. And what happens if #VisionPro continues to flop and we all forget about it, but we’re stuck with its design language?
