Your point is decent, it is definitely hard to find another people with similar desire, but I do not going to rid of my computers btw.
Instead I am going to get an extra computer (a typewriter is considered as well) for my garage where energy shortages is a common and where I use to work at some technically-loaded hobby projects. That's why I afraid that the computer will interrupt my workflow via begging too much of my attention. So, I hope to exchange all multimedia options for instant power-up to end up with a typewriter with editing option and nothing more.
I think in that case an iPad might be a good companion as it has a long lasting battery, can be carried around and if it's a dusty environment it doesn't have big problems with that.
Would also make it easy to keep backups if you just take it back into your wifi/power area of the house from time to time to charge and sync.
