Recently, I've begun to realise that nearly everything that can be done in Illustrator can be done in InDesign and more productively. It got me thinking. I know that Adobe won't be doing it any time soon, but why not just combine Illustrator with InDesign? So many of the features of both applications are the same, with a few exceptions such as InDesign's print-specific qualities. But overall, I don't actually see a reason why the two applications are separate anymore. Macromedia's Freehand was almost the parent of Illustrator and InDesign, as I've recently been discovering. The ability to create a multi-page document along with artistic renderings was all contained within one application and from that, Illustrator and InDesign were born. But was there a need to separate the two? I realise you could argue that you might as well bundle Photoshop into that equation too but Photoshop is bitmap-specific, whereas InDesign and Illustrator follow the same sort of laws when it comes to illustration and print design. What do you think? What redeeming qualities does Illustrator have over InDesign? Does it have enough features to make it worthwhile having it as a completely separate application to InDesign or can you see how both of them could be incorporated into one?
