It can be said that Apples are among the smoothest running out of the box, but does that really mean there's no crap? This line of reasoning begs the definition of "crapware," and the #1 response would be "stuff you don't need on your computer." It doesn't have to slow it down, it doesn't have to have an enormous memory footprint when it's running or a huge disk footprint when it isn't, it just has to be stuff you don't need. And depending who you are, that can be quite a lot.
Have you ever used iWeb? iDVD? Some would consider the whole iLife to be crapware because they plan to get higher-end, more professional applications through which to vent their creativity. And if they're thinking about office use, they're likely to go the route of Microsoft Office / OpenOffice, so bang goes Pages, Numbers, and Keynote. Do you ever plan to serve web pages up from your laptop? (Well, I do, but then again, look where I'm posting.) You probably don't need that install of Apache or PHP. Not planning on doing any software development? Yes, XCode is an optional install and not part of the standard kit, but you've still got perl, ruby, python, pico, vi, emacs, and more shells, libraries, and frameworks than you'll ever need nestled down in /usr/local. Have a digital music library already? Then you might also have a preferred player, and probably won't want iTunes to re-rip it into that silly AAC format. A lot of people despise Quicktime on general principle. And a lot of people still eschew Safari for Firefox despite its HTML5 support.
It all depends on your definition of "crapware." It's all assembled and designed by the mother company, so it's integrated so perfectly that you're never bothered by it if you never use it, but if you dig, you'll find something that'll fit the description.
