I enjoyed it for a few years when I had an income from other sources than art. If you have good art skills and are tech friendly, and have the money to play with, it is fun. However, as a synergist, to analog, not so much more than using a paper sketchbook religiously. My hands really prefer brushing paint freely on a large canvas rather than working on a small digitizing pad and pushing buttons. I have not changed to the touch and swipe screens, so maybe a large size one of those would be more fun.
It is a time saver when doing a lot of black and white illustrations in a hurry. But the look is not the same and marketing is totally different than selling an original painting.
