I want a "forever computer" and I think this fits the bill. I don't actually expect it to last forever, but with unix command line tools we've got one lineage of computing that has lasted more than 30 years. I want to put a solar panel and a lora modem on it, and have a little computing device that will last the rest of my life. An artifact that will be as useful in 40 years as it is now, like how old calculators with nixie tubes still fundamentally work as calculators.
Might even try finally learning orgmode, maybe use vim-orgmode one it.
For similar reasons, general future proofing, I recently started using orgmode for my todo lists, journaling and a light project management workflow. I'm a vim person, and using spacemacs with evil mode has been good for learning. I imagine I'll eventually start from scratch and only keep the pieces I like, but it's been a reasonable starting point.
This looks great for those purposes, it should interact nicely. There's a decent chance I'll pick up the watch today. (Can I make it buzz for pomodoro? Hmm.)
