I’ve got my Urbit running on a native planet hardware box (https://martiancomputing.substack.com/p/product-review-nativ...) plugged into my router’s switch that I can access from anywhere. The UI for groups also looks good on e-ink (mostly white and black, nice design) one of the devs has an e-ink phone that shows it off. It’s cool to really own the entire stack.
I had the original remarkable tablet mentioned in the post and it was really cool (someone was also using it as a browser to access urbit back then), the new tablet looks better too.
There was someone at the first urbit assembly (probably here on HN) working on cool new e-ink style tech that had some advantages without having to engage with all the patent nonsense and vendor lock-in that has plagued (imo seriously stalled) e-ink as a technology.
