I'm sure you can. I think probably I'd be fine with it if I sat down and used it every day for a week or two - it's just that because I do quite a lot of old fashioned drawing with pencils, and a lot of mousework, the muscle memories of my hands are all wrong for the tablet, and I need to find an extended period of time where I can find a new mode for them.

It may not help that as I use a good gaming mouse which is very precise, the increase in precision I get from the pen is not as noticeable, so the incentive to push on is less!
