Jay J. Nelson wrote a nice overview of Adobe InDesign CS5.5 for Macworld. InDesign is my favorite Creative Suite app and the one I’m most familiar with. I still use CS3 (though I haven’t yet installed it onto my MacBook Air, and even when I do I’ve heard rumors that I won’t be able anyway), but with these new digital publishing tools that InDesign CS5.5 has it may be worth it to upgrade.
