Adobe Illustrator CS4 review by Ben Long, Macworld.
"If you're someone who started out with Adobe Illustrator back when it was called Illustrator 88, then you've seen lots of changes over 20 years. Illustrator is one of a handful of powerful vector drawing products aimed at graphic artists and illustrators, and it's always been elegant and production-ready. Even if Adobe has sometimes been slow to add cool new features, you could always count on Illustrator's stability and its color and output engines to perform well in a professional production environment.
Illustrator, as a high-end professional app, doesn't really have any competition on the Mac anymore (CorelDraw is Windows-only), which might explain why Adobe is only now getting around to adding some features that the program has needed for years. If you're a Mac user who needs a vector-based drawing tool, Illustrator is the biggest and best player around, and the new CS4 version is a solid, impressive upgrade that adds some cool new tools" Full review
