I have thought about the usability of rollable screens in computers. There have been a few prototypes and I have posted two below the two points below this text and I have been enthusiastic about this tech. Though they look good I have realized two things :
1. They cannot be used in outdoors environment where there is dust, water, fog, oil in air ( in industrial settings ) etc. These external elements will get into the space from where the screen is being pulled out and enter the circuitry.
2. It will be inconvenient to write something into an application using a cell phone style virtual keypad or a handwriting-recognition / free-drawing system using a pen, because the rollable screen has to be held in pulled-out mode using both hands. This contrasts using a cell phone where both hands can type while holding the phone or in a tablet where one hand holds the tablet and the other can use the pen.
I think it is better to design a computer of the form-factor of slightly more than a cell phone but provides not a rollable but a foldable screen. Like in
this device from BOE.

For contrast :
1.
This article and vid about a rollable screen + cell phone called MagicScroll from Queen's University, Canada, from 2018. I post this vid just to demonstrate that a rollable screen can be afixed with a rollable touch screen for interaction too.
