I've heard that Adobe InDesign has some problems on mac, don't know if these problems are solvable. If you are a student (or have a son/daughter who could buy it for you), you could get large discounts on Indesign, so that might be something to look at.
Really? I have never had a problem on InDesign on a Mac. At school we used InDesign CS2 and it worked perfectly on the iMacs. I liked it better than QuarkXPress since it worked so well with the other Adobe applications.
I thought I heard that InDesign CS3 or CS4 has problems with file saving or printing, making it almost impossible to save the things you make. However, I could be very much wrong.
