From the day Apple first announced Mac OSX, the company made clear that Mac OS X offered a lot of advantages, particularly in stability—but that you would need all-new versions of your programs to realize these benefits. Most software companies announced that they would get to work Mac OS X–izing their programs, but Mac fans kept reading the same advice: Don't switch to Mac OS X until most or all of the programs you use every day have been adapted to run on it.
For most people, that time is here. One by one, the Mac OS X versions of big-name programs became ready: Microsoft Office, Photoshop, InDesign, QuarkXPress, iMovie, iTunes, Illustrator, Freehand, Quicken, FileMaker, Internet Explorer, and thousands of others. In fact, most of the latest Mac versions run only in Mac OS X.
