My vision of a  ALL-in-ONE  machine is a  machine that combine a  Laptop with a  Tablet and with a  Smartphone , and if possible , with a  DVD-RW Player  built-in , which I would like to call                                                                                           [ Laptop/Tablet/Smartphone(All-in-ONE) with built-in DVD-RW Player ]   

• Basically , an   ALL-in-ONE  machine  has to be thin ( not too thin because it has to accomodate a DVD-RW Player ) , light , slim and sleek and reasonably powerful ,  which can serve as a Laptop , which can serve as a Tablet and which can serve as a  Smartphone , that we can use for work , study , play , education and entertainment .

• Basically , an   ALL-in-ONE  machine  can be a   4G LTE   Cellular   Laptop ( regardless whether it is    " foldable  360 degrees "   or   " detachable "   ,   regardless of screen  size ,  regardless whether it comes with built-in   DVD-RW Player   or  without   built-in   DVD-RW Player  ,   regardless of the Operating System it uses ) which we have in the market today in  February 2023 , but it has to be re-engineered to be able to make phone calls , voice calls , just like an Android Smartphone ,  that we can use for work, study , play , education and entertainment .   [ 1 ]

• Basically , an   ALL-in-ONE  machine  can be a   5G   Cellular   Laptop ( regardless whether it is    " foldable  360 degrees "   or   " detachable "   ,   regardless of screen  size ,  regardless whether it comes with built-in   DVD-RW Player   or  without   built-in   DVD-RW Player  ,   regardless of the Operating System it uses ) which we have in the market today in  February 2023 , but it has to be re-engineered to be able to make phone calls , voice calls , just like an Android Smartphone ,  that we can use for work, study , play , education and entertainment .   [ 1 ]

• Basically , an   ALL-in-ONE  machine  can be a 4G folding smartphone ( a typical example is this and this ) or a 5G folding smartphone ( a typical example is this and this ) which we have in the market today in  February 2023 , but it has to be   re-engineered in such a way  that it can be unfolded into a 15 inches Tablet because with that 15.6 inches form factor , a folding Smartphone can also be a 15.6 inches Laptop and it can also be a 15.6 inches Tablet and it can also be a  15.6 inches Smartphone which we can use for work , study , play , education and entertainment . Even though a folding smartphone doesn't come with a built-in DVD-RW Player , but by connecting a Docking Station to the folding smartphone , a DVD-RW Player can then be connected to the folding smartphone . Isn't it great ! As of today , February 2023, there is no commercially available folding Smartphone that can unfold into a 15.6 inches Tablet . As of today , February 2023 , " folding Smartphone that can unfold into a 15.6 inches Tablet "   is one computing device that has yet to be invented, regardless  whether it is   INTEL-based or  ARM-based , regardless of what Operating System it uses , etc., etc.
