I guess the question is: What do you do? In my case it spans a range from typical office/email applications to mechanical 3D CAD, software engineering, electronics CAD, various specialized manufacturing tools/applications and graphic design software. It's varied enough that there's no way I could use a Wacom tablet (I have a few). The trackball seems to be the best common denominator for everything but running tools like Photoshop/GIMP/Corel. In that case the preference these days for us has shifted to drawing tablets with built-in displays (https://www.xp-pen.com/ https://www.xp-pen.com/).
