Microsoft announced this month that it will be discontinuing the Windows Subsystem for Android — the thing that makes it possible to run Android apps on Windows PCs — in a year’s time. The feature wasn’t used by many, but that isn’t the fault of Windows users. Android apps were irrelevant on Windows because the implementation of them was fundamentally unintuitive. A feature that enables phone apps to run on a desktop operating system is the kind of thing only Apple can do well thanks to its unparalleled cross-platform integration.
