The ability to answer phone calls would give you one less reason to pick up your phone.
Windows users with Android devices already have this option via Your Phone, and macOS users with iPhones, iPads, and Apple Watches have the same ability with the Continuity feature.
While Phone Hub supports phones running Android 5.1 or later, the new feature may only be available to Pixel phones—at least initially.Considering Google makes both Android and Chrome OS, it would be odd if Windows was more welcoming of different Android phones than Chrome OS.
