I am using my laptop to take notes in class and would like to use my android based e-ink tablet for quick handwriting and diagrams. What is a good way to get the content from the tablet to my vault as quickly and smoothly as possible? First-party sync? Note files pushed through Syncthing?
I do not think that sync or syncthing will be fast enough. And if you jump here and there, you can get versions conflicts. Either use different notes and later merge or purchase a BT keyboard to your tablet and use it for typing.
Using a laptop and a tablet in a class sounds a bit overengeneering.
