I have used it with my tablet pc. It is a fun program. I have one map where I used it to make a cliff face and waterfall. It worked pretty good for that. I would love to have more time to play with it. I wish it did watercolor as well as oil based paints, I have been looking for a program that would let me make watercolor tinted symbols well. I fiddled with painter X, but it cannot do transparencies when using it's watercolor mode.
I have attached what I did with it. The map is mostly CC3, with SS2, but the cliff and waterfall I did with Artrage2
