I got a small Wacom tablet about 10-15 years ago. Tried several times to get used to it but I have been using a trackball for too long and at my age muscle memory is important and hard to develop. It looks like it would work well and so many people swear by them it's probably a viable editing tool, just doesn't work for me.

OTOH, I gave up the mouse about 3 decades ago and switched to a trackball. The mouse requires desk space and the trackball does not. You can even use it under a pile of papers on your desk. My desk was always messy so the trackball worked for me. Over the years I have had several different kinds and my favorite right now is the Ergo from Logitech. It comes in two packages. The best one is about $75-100. It has a two-speed trackball. There's a button right by the ball that will switch to fine motion so you can get more accuracy from the motion. It also has a switch that will allow you to use it on one of two machines, so I can put two laptops side by side and use the trackball on one or the other without moving my hand. It's wireless bluetooth and has a USB port for occasional charging.

I find it really good for editing because of the fine control. But that's just me. I would put it out as an option in case the tablet doesn't work for you. Both items take practice.
