This is what I do for my presentations (on a wacom of course). I have gotten grief over it, but I work faster and get less distracted by the eccentricacies of powerpoint and figma. My handwriting is abysmal so I will do that in a "handwriting font" to sort of look hand drawn. Even if I have to convert them later for some big wig, at least I have my "rough draft". Plus it all feels a little more human.
