- iPod + iTunes
- .Mac
- Quicktime
.Mac and Quicktime were actually two of the most prominently featured products on Apple.com. Wow. iPod and iTunes have stuck around but are now treated separately probably due to the variety of content available on iTunes (apps, books, movies, games).
I find it strange that Mac's aren't featured on the 2004 navigation bar. Instead it's OS X.
