I'd like to have a PDA, like in the old days. By a PDA, I mean a portable computer, fitting in a pocket, which would be capable of making notes etc. I'd like to be able to access a wifi network to sync files, but I don't need nor even want cellular connectivity. An important thing is that it should run neither Android nor iOS, so that there won't be a possibility of distractions like games. I'd also prefer it not to have a web browser (for the same reason). Ideally it would just boot into Emacs with Org mode;-).
I found https://www.clockworkpi.com/uconsole (btw, any opinions about it?), and it seems it would be exactly what I want, but are there other options?
