I realized there was already a device that was perfect for note taking on an infinite canvas.
I use an iPad and Apple Pencil (bought refurb on backmarket.com) with paper like surface [1] I install nothing in it except Apple Freeform. (No distractions)
High refresh rate, Retina display, excellent pen pressure, and fast chip. Cheaper than RM2 if bought refurb.
How do you uninstall Safari? That's the most distracting app of all.
Open Shortcuts.
Go to Automations.
Create one, for App, when Safari is opened, run immediately.
Create a new blank shortcut.
Add one action: go to Home Screen.
Now when you open Safari, it instantly closes again. You can disable that by turning off the automation. It’s more of a slap on the wrist than a handcuff, but a reminder that you don’t want to use the app on that device.
I'm a mathematician and my "creations" are small notes, comments, and very simple figures.
I've never (besides flipping pages) experienced any noticable lag or delay.
I find the page concept limiting (for me). I scrawl something but I need an infinite canvas to relate multiple ideas (my mind doesn’t work so linearly). That’s when refresh rate matters a lot.
Also matters when skimming. Eink displays are not conducive to skimming over many pages. That problem is solved on LED displays and paper, but not epaper.
