I know. But drawing on a table can be... confusing. That you have to draw on the tablet but look at the screen is kinda confusing, and if you dont have some practice on drawing already, it can make things more complicated. besides, art can be awesome too with only a pencil and a piece of paper. Even such simple tools can be enough to do awesome things. I mean, just look arround here on DA, you will find lots of art made only with a black pencil and paper.
