I also have a similar vision. A miniature NAS/desktop, from where I can ssh to a light-weight, battery efficient laptop. And a modular, chonky Thinkpad-like cyberdeck with good battery, for on-the-move hacking. Localized compute unit, with the option to house multiple upgradable, System-on-a-Module may be a part of the modern smart-city home as a default , I'd guess?
