Apple products you're forgetting include: iMac, MacBook, MacBook Air, MacBook Pro, Mac Mini, Mac Pro, all the iPods (four types, I'm not gonna list 'em all), the iPhone, various keyboards, Apple TV, Time Capsule, Quicktime, iLife, Aperture, iMovie, Final Cut, Mac OS X Server (if we're going to count every permutation of the OS separately), Logic Express, GarageBand, Shake, WebObjects, and probably a bunch more.

It's true that Microsoft has more products in each category, but Apple (as a hardware/software/consumer electronics) company covers more categories.
