Honestly, I've been using a remarkable tablet for reading papers and also as a notebook to jot things down or to work out problems. It's fairly convenient and I think having a pen/paper like experience really helps with retention. Since it's pretty limited on what it can do (e.g. no notifications/no apps really), it's a fairly distraction free experience.

There's other tablets/systems that work similarly and tbh, I think having no apps or limited accessibility is really a bonus for this type of work.
