Foldable PCs are still alive and kicking but foldable PCs that can do voice calling like an Android Smartphone are still not available yet .  

A good example of a Foldable PC that I envision which can do voice calling like an Android Smartphone is a [ 15.6 inches INTEL-based   “360 degrees foldable”   Android OS

Laptop/Tablet/Smartphone(ALL-in-ONE) with built-in DVD-RW Player ] which has not been invented yet .

A [ 15.6 inches INTEL-based   “360 degrees foldable”   Android OS

Laptop/Tablet/Smartphone(ALL-in-ONE) with built-in DVD-RW Player ] unique selling point are :

1.   It is a  Laptop but at the same time  it can also be a  Tablet and a  Smartphone (just

like an Android Smartphone) .

2.   It is  a  Tablet  but at the same time it can also be a Laptop and  a  Smartphone (just

like an Android Smartphone) .

3.   It is a  Smartphone (just like an Android Smartphone) but at the same time it can also

be  Laptop and  a  Tablet .

4. It has a 15.6 inches screen size diagonally

As of today , Sunday 9th.January 2022 , this machine has not been invented yet . Hopefully or eventually , some  hardware/software  manufacturer will find a way to unify the disparate experiences across   Laptops/PCs ,  Tablets , and  Smartphones   by  inventing a    Laptop/Tablet/Smartphone(ALL-in-ONE) , regardless of screen size , regardless of what   processor/microprocessor  it uses , regardless of what Operating System it uses , regardless whether it is   “ foldable 360 degress “  or     “ detachable “ ,    which we can use on a daily basis , for work , study , play and entertainment .
