Well considering how badly paned the JooJoo was (not just for it's lame Flash support but everything else about the UI) it makes sense that Notion Ink doesn't want to follow the same fate.
Of course with Adobe's latest post distancing themselves from the JooJoo, I'm wondering if Notion Ink is directly working with Adobe or not?
