It's a source of delight and frustration how much computational capability everyone has now, and how much of it goes to waste.
Planning out a household budget; keeping a running grocery list; planning a garden planting schedule; tracking health data; reading and writing email; maintaining a calendar of event reminders; managing a contact list of the addresses of friends and family; these things need so little processing power and storage that it's almost comical. A Pi Zero could suffice.
@neal right?? I'm doing almost all of my "serious" work under emacs these days, a not-insignificant amount of it under termux on my phone. My aggregate power consumption statistics show that even the *keepalive background tasks* are obliterating the fraction of the power budget I'm spending on the things I actually care about!
