I actually have the feeling and I hope I will be wrong but AS copies Adobe already.
Why have an illustration tool and then a publisher tool? Ever worked on multiple page documents?
Try that in InDesign it is a disaster when you need to work on something that is not a book.
Freehand was perfect for that and Illustrator at one point got the artboard feature but of course lacking the master page tools.
And I feel AS does the same some illustration here some layouting in a different app enjoy pushing your data between the apps.
I really hope I will be wrong with this fear.
