This sounds great, but it pains me that I can't dual-boot my iPhone 15 Pro as a lightweight Mac. Would be great with an HDMI connector & BT keyboard/mouse.

I can't see Apple doing anything that'd make the iPhone not a usable phone while it's being used as a Mac. But I bet they could have macOS components running alongside iOS, in a VM/container of some sort. Would be very cool.

(Honestly I can't see Apple doing that either though since it'd cannibalize their other product lines. But c'mon, Apple!)
