I imagine in near future, we will use smartphones as our personal computer in every situation. In the office, one can then interact with a Bluetooth keyboard, mouse/touch pad and use a big monitor. Probably, one of the next iOS will come with a macOS UI as well (under the hood the iOS is based on macOS anyway) - so if you connect it to a huge monitor, you have the desktop UI of macOS, and otherwise the iOS UI. The same will happen with Android/ChromeOS/Google Fuchsia, Ubuntu and MS has some ideas too (but they cannot execute it, forcing mobile UI on desktop failed big, now they bet on Win32 again to fill their empty AppStore).
