That did occur to me reading through this discussion.

I migrated entirely off desktops and went laptop / mobile.

Got happy as my current work benefits from me being highly mobile. Super glad I did it. Ended up surprised at just how much can do with a Note type phone and optional keyboard / track pad.

But, I never did replace fast and responsive. Just kind of coped and the other benefits made the whole thing worth it.

This pandemic has me rethinking some things and yeah, I want to build a nice machine. Want that workstation type feel and performance.

The closed computing argument holds more water every quarter too.

What we need is a reasonable battery pack, and software to throttle the machine down on an interruption. Make this package a couple hundred bucks, or something a person can just load their own cells into and it's bound to be a winner.
