I play an in-person Pathfinder game at a friend's house who has a projector on the ceiling to make maps on the gaming table, and that's all he was using it (and roll20 off a laptop) for - making maps (and more recently, initiative tracker). I'll be GMing the next campaign, and I want to use roll20 for a fuller breadth of its functions. I'm going to be setting up the sessions on PC, using the projector laptop to run a single player-version of the session (hiding unexplored rooms, etc), and then bringing a separate device to run the GM session, so I wouldn't be running a game where the players are directly playing off the roll20 session. How well does Roll 20 run off of a tablet/touch screen? I would just be running it through the browser on the tablet. When I search for this question, I get 1) threads from more than 5 years ago and 2) people talking about it in a way that looks more like they're talking about how good it is on a tablet in all aspects of roll20 (running + setting up + playing the game). Would a tablet be fine, or would I be better off using a laptop for game sessions?
