With the advent of new semiconductor technology , 5G , IoT , nanotechnology , neural networks , etc., etc., and new manufacturing process , I believe ,   with some engineering effort , it is possible , to incorporate the features of a telephone into  a  Laptop so much so that we can call them Cellular Laptop or 5G Cellular Laptop . 

The 5G Cellular Laptop , that I envisioned , which look something like this , should natively support voice calls like a telephone , like a  5G smartphone .

After all we only want to make crystal-clear phone calls and receive crystal-clear phone calls with our 5G Cellular Laptop , just like  the GSM calls we make with these devices [ 1 ] many years ago , so much so that ,  most of the  Android apps  sitting inside our  5G smartphone  is not required to be inside our 5G Cellular Laptop , is not required to be installed inside our 5G Cellular Laptop .  Because all the  Android apps   sitting inside our  5G smartphone will not make our voice calls inside our 5G Cellular Laptop crystal clear .
