Ok, I have to clear some things up. Someone mentioned that they love Photoshop interface but hate Illustrator interface. Obviously, that person was either talking about a different Adobe product (Imagestyler?) or never used Illustrator because it is basically the same interface as Photoshop. Also, Illustrator is vector-based drawing program so there will be no merging with Photoshop any time soon. Otherwise you might as well buy Canvas which is basically like the two combined.
