I am afraid of one thing, and one thing only: a lack of software being developed for OS X. It seems like something's happening, but everything I see so far is either a totally new Cocoa app that does basically nothing, or a Carbonized app that runs perfectly in OS 9 and has billions of bugs and sloppy features in OS X. I also see programs that are still being developed for OS X, that will be big, like Photoshop. But that still doesn't make it a diverse OS. I can still name all of the titles that I'll be expecting and I can expect, and developers might lose the OS X spirit because not many macintosh users have the specs to run the OS. For acceptable performance you'd need a very high end iMac or a low end G4. Although I am not sure of the grades of machines macintosh users have on average, I am worried that OS X is too far ahead of it's time, and people won't respect and develop for it as much as they should.
