Typically I use pen and paper, but I’ve been interested in a tablet or similar device for a while and am interested in what other people are using.
The reMarkable 2 seems like a really cool option to play with, but also pretty pricey for trying it out to see if it would even work well.
While it’s not directly related, when playing in games, I usually use a paper character sheet for reference, a notepad for consumables, story notes, and HP, and Pathbuilder on my phone for spells.
The iPad is in landscape mode and to the side of the laptop. I keep them both behind a GM screen.
I actually came from vim and use vim keybindings in eMacs. It’s the best of both worlds. Vim has an org plug-in but it’s really just syntax highlighting and you lose the power of it.
