You should - I think some people do really amazing work with it but for me the hardest part is that you are not actually looking where you are drawing - it seems to screw up the hand eye co-ordination for me. Plus the pen that you have to use is nothing like a brush and it can't replicated the different shapes that different pens, pencils and brushes have as a physical object. There is one pen and you use it for all brush sizes and types so you lose a lot of the feel of actually using a particular type of brush or pen. The advantages are that it is much cheaper, cleaner and you can mix all kinds of materials that would be impossible in real life.
