It seems to me that it would be more natural way to do a standalone drawing rather then a pad where you are drawing in one place and looking at you monitor to see the image. I get so messed up trying to use my wacom. But it's a really old 4x5 intous 2.

The downside is unless you use the layers feature it is, as he mentions in the video, no different from drawing in your sketch book and then scanning the image.
