Livescribe just picks up "you drew a line here". For an artist, this is not enough. You need to pick up how hard the line was drawn, you need to pick up pulling out colored pencils or markers or paint and poking at your sketchbook that way.

I personally don't do much finished work in my sketchbook - I'm all about Illustrator - but a lot of my friends still love traditional media, and will casually whip out something amazing in their sketchbook because it's what they have to work on when the urge strikes.

Artists are an extreme example, a non-artist still might be using multiple colors for their notes and whatnot.
