A 10" screen is 71 inches square. A square foot is 144 inches square. You are saying your working area is about 10 square feet and ergo nobody could possibly want the same applications on a machine with 2 27" monitors as one 10" or even 6" screen despite many tasks being useful on both because SOME tasks are not.

An absolute ton of people use actual computers with 12" - 14" screens including for complex tasks they just switch tasks more which is probably less efficient but hardly impossible.

They may opt to dock their machine at home/work for a larger work area but as it happens many tasks may cross both environments.

For example at home you may have many windows visible at once one of which is a document you are reading or a video you are watching another an editor in which you are writing documentation or code. After you undock you may wish to continue SOME of the tasks on the smaller screen for example watching the video or reading the document but opt to defer others until you have richer input and display options.

Lets go a level deeper. Your device is a general purpose computer. It could in theory run 2 entirely different UI stacks that run on the same OS and access the same files. Its the files that are the vital thing. If you create a video in one stack and merely watch it in another what of it.

Convergence is merely the idea that you will eventually be able to carry a small enough cheap enough computer in your pocket that it wont make much sense for many people to lug around 2 different portable computers.

This seems as inevitable as computers going from buildings to something we lug around in the first place.
