I would be so glad if there is a hardware/software manufacturer who are willing to make this kind of device or this kind of machine , which I call a  Cellular Laptop .  An example of a Cellular Laptop or a Cellular Laptop machine using Android OS which I envisioned   is  a   "15.6  inches   Android OS  Laptop/Tablet/Smartphone(All-in-ONE) "   which  have the physical appearance of  a   " 360 degrees foldable laptop "  [ 1 2 ] or  have the physical appearance of a  " detachable laptop "  [ 1 2 ] .

  This  Android  OS  Cellular Laptop  can be  an alternative  to  the  Android  Smartphone because this Android OS Cellular Laptop can be a  Laptop and it can be a Tablet  and it can be a  Smartphone . (which most of us already have  right now) .  

This Android  OS  Cellular Laptop  doesn't have to be made with insanely good hardware .   This  Android  OS  Cellular Laptop  doesn't have to be made with cutting edge specifications .  This Android OS Cellular Laptop doesn't  have to be made to be a premium device ( with a premium price tag and so expensive ) and aim for business/corporate users  but it should be made with reasonable hardware specifications  for ordinary users that are easy to use and easy to understand , who love the extra screen size ( 15.6 inches of course ) , who love the large on-the-screen keyboard , who love voice calling ( regardless whether it is a 360 degrees foldable Laptop or a detachable Laptop or a Tablet ) , who love the simplicity of an   OS/GUI   which  have the same look and feel regardless whether it is a Smartphone ,  or a folding Smartphone ( a folding Smartphone that unfold into a 15.6 inches Tablet ) , or a Laptop , or a Tablet or a Laptop/Tablet/Smartphone(All-in-ONE) or a SmartTV , which they can use for study , work , play , education and entertainment , on a daily basis .
