With the current Coronavirus disease (COVID-19), many of us had to switch all our activity to full online mode.
I am wondering whether some of you had the chance to use graphic tablets. I am looking in particular for advice regarding the best model of graphic tablet for math (in particular, for research, giving online seminars, teaching, etc).
I am not looking for expensive tablets with a screen (such as ipad or similar), but simple, possibly not too expensive, graphic tablet.
