Call me a 40-year-old boomer but...
This would be a perfect scenario for Steve Jobs to give a live keynote and at the end say that there's "One More Thing…"
And then he says, "In a secret area of our offices, in that building, we have been creating a version of macOS that runs on iPad. We have done it with every release. And with macOS 15, we think we have it right. Introducing macOS on iPad."
And then the crowd starts cheering.
And I would also guess that only people roughly my age or older can truly appreciate this dream as it reminds us of the PPC transition Keynote and the reality that the Mac and the Mac OSes are what's made all this possible. Those who don't understand, I humbly predict, never had a Macrumors account pre-iPhone or stared in appreciation at a pulsing Aqua blue OK button when Mac was awake and a pulsing white light when Mac was asleep.
