I'm really impressed. I think that combining it with CS5's amazing brush setup I'll be able to bypass a lot of analog process work and jump straight to digital. This will save time and add flexibility while still preserving the looseness of hand rendering. Also it's essentially the same techniques, so you stay in practice with sketching even though it's not a piece of paper you are sketching on.
