I can’t wait to try the Illustrator. Do you know that you can control the width of a brush strike without expanding it’s appearance? You can even set the dash marks to get in the corners of a path rather than try really really hard to do it yourself. Check out a sample video here: http://www.adobe.com/products/illustrator/design/?configListID=0&chapterID=0&npObjID=1
I’m really aiming for the upgrade on the design premium package. There are a lot of other cool things the other programs do to, like Photoshop’s new content aware option. It’s so great.
