In the computer industry , I believe , a  [Laptop/Tablet/Smartphone(All-in-One) with built-in  DVD-RW Player ]  is a true and a real 3-IN-ONE machine or a true and a real-world productivity machine because it combines the capabilities of a Laptop and a Tablet and a  Smartphone into one machine , into one device , which makes it multi-functional .

A   [Laptop/Tablet/Smartphone(All-in-One) with built-in DVD-RW Player ] machine is more than just a  Laptop, is more than just a  Tablet, is more than just a  Smartphone. It can serve as a  Laptop , it can serve as a  Tablet and above all it can serve as a Smartphone (can make phone calls and answer phone calls just like a  5G smartphone and can do all the  smartphone-related stuff just like a  5G smartphone).

The  [ Planet Computer  15.6 inches  Touchscreen   triple-boot   Astro       "360 degrees foldable"     INTEL-based  Windows 10   5G   Transformer Smartphone with built-in DVD-RW Player ] is a good example of a  [ Laptop/Tablet/Smartphone(ALL-in-ONE) ]  machine , which I envisioned ,  made by  Planet Computers .  

The    [ Planet Computer  15.6 inches  Touchscreen   triple-boot   Astro       "360 degrees foldable"     INTEL-based  Windows 10   5G   Transformer Smartphone with built-in DVD-RW Player ]  machine , which I envisioned ,  made by  Planet Computers , combines the capabilities of a Laptop and a Tablet and a  Smartphone into one machine , into one device , into one unit , which makes it multi-functional .  It can serve as a  Laptop , it can serve as a  Tablet and above all it can serve as a Smartphone (can make phone calls and answer phone calls just like a  5G smartphone and can do all the  smartphone-related stuff just like a  5G smartphone).

 The    [ Planet Computer  15.6 inches  Touchscreen   triple-boot   Astro       "360 degrees foldable"     INTEL-based  Windows 10   5G   Transformer Smartphone with built-in DVD-RW Player ]  can be a  5G Smartphone in a  LAPTOP mode when it has the physical appearance of a Laptop and it can be a  5G  Smartphone in a TABLET mode when it has the physical appearance of a  Tablet .  Meaning , we can make phone calls and answer phone calls , directly from  the  [ Planet Computer  15.6 inches  Touchscreen  triple-boot     Astro       "360 degrees foldable"     INTEL-based  Windows 10   5G Transformer Smartphone with built-in DVD-RW Player ]   just like a  5G smartphone(in LAPTOP mode , in TABLET mode , in TENT mode , and in   THIS MODE ,  etc., etc.).

The   [ Planet Computer  15.6 inches  Touchscreen  triple-boot    Astro               "360 degrees foldable"    INTEL-based  Windows 10   5G Transformer Smartphone with built-in DVD-RW Player ]  machine , which I envisioned ,  made by  Planet Computers , operate like  5G Mobile phones  and their SIM cards are interchangeable with 5G smartphones , meaning , we can pull out the SIM card from our 5G smartphone and swapped back and forth with the   [ Planet Computer  15.6 inches  Touchscreen  triple-boot    Astro       "360 degrees foldable"     INTEL-based  Windows 10   5G Transformer Smartphone with built-in DVD-RW Player ]  to make phone calls either with our  5G smartphone or with our   [ Planet Computer  15.6 inches  Touchscreen   triple-boot    Astro       "360 degrees foldable"    INTEL-based  Windows 10   5G Transformer Smartphone with built-in DVD-RW Player ] .
