>An iPhone that’s able to project something more like iPadOS (or, ideally, but not definitely wishful thinking on my part — macOS) when connected to a screen could easily replace a laptop for probably a significant portion of the population, including for casual computing, and for the work tasks of the bulk of the knowledge workforce.<p>No, it wouldn't, because you'd need a display and input device(s) at your destination. So then we ended up with these laptop-style shells for Android and Windows Phone devices that supported this model and suddenly you can't use your phone separately while you're in laptop mode. It's easier to just bring a laptop/Chromebook with you.<p>There's no need for the device's local storage when you're already syncing important documents to the cloud anyway. This is a "cool" solution in search of a problem.
