What I really want is for my state (SSD, RAM, maybe the CPU, but probably not the GPU) to be easily detachable from my human interface devices (keyboard, mouse, display). I want to be able to use a desktop in one place, then unplug a small unit which contains the aforementioned state (i.e. the equivalent of a sleeping laptop but with no keyboard or display), carry that someplace else, plug it in to a different set of…
I would go a bit further: I want my state to be inside a seamless hardware agnostic VM, that I can access anywhere through public terminals that I only partially trust. I would have the option of either having my storage with me that I plug in, or in the cloud and I just provide 2fa. My device would have a cpu/gpu/etc befitting a mobile device, and the most barebones / untrusted terminals would just be screen/inputs/…
