Are we headed to having a portable device (tablet or phone style) able to be docked to a station, where upon docking, the tablet then becomes a PC running a more powerful CPU and a different OS?
Such as Android (windows) or iOS as a tablet, docked could run MacOS or Windows or Linux/Unix? iOS hooked into Windows or Android hooked to Mac OS?
Maybe the tablet CPU could handle both docked and undocked situations, the station providing more memory, both RAM and data storage, interfaces etc.
Maybe the tablet could act as a boot device for the station (done before, eg. DEC mainframes).
