honestly, the only feature worth adding is macOS dual boot. You can already do so much on your phone that is so absurdly Byzantine and unergnomic on a tiny touchscreen, I have no desire and no one should have a desire to do serious video editing or whatever on a what 6” screen. But if the hardware supports it, sell a phone with 2 TB ports that boots macOS when a display and input devices are connected. Make that the pro model, sell it for like $1500+ because it replaces your MacBook, offer a super overpriced keyboard/trackpad/display/extra battery dock that’s essentially a MacBook without the compute and you can capture the income of selling an iPhone plus a MacBook Air all with only one A series chip lol.
In all seriousness, iOS iPadOS MacOS and VisionOS being strictly separate branches of the same OS just to silo hardware sales is getting absurd — one high spec SoC that can switch which front end of the Apple OS it can display based on the connected I/O is the sane solution except that we live in hell where selling more widgets is the only meaningful metric, wastefulness and duplication be damned. I have 6 devices running apple Silicon that I interact with every day, including an AppleTV that basically only exists to be a home hub. A MacMini that mostly exists to be a content server and media ingest solution then one device for each of the 4 OS flavors — from a practical standpoint there’s zero reason I need more than 2 or at most 3 SoCs for these functions. (TV and Mac Mini should merge of course, then the brain of my phone should be able to run all 4 OSes depending on if it’s docked to a 6”, 11”, 16” or head mounted display.)
