If they can add more illustration capabilities without compromising the ease of diagramming, that's fine. But it would be impossible for me to do my job in, say, Illustrator or Freehand, even though I'm proficient in them. I'd spend too much time manipulating elements at the point level, or just have too many style choices at my disposal, distracting me from the information design. For years, before adopting OG, I used Powerpoint, which is an awful drawing tool, but that's exactly what made it a quick and efficient tool for diagramming. (It also has a terrible user interface, so I was always looking for an alternative.)
