I own an Intel Mac Mini. I also am used to using Linux ports. Apple's download site is NOT the first place I look for software for my Mac. In fact, the only thing I remember downloading from there is OpenOffice.org and the only reason I downloaded it there is because the bandwidth on the main OpenOffice.org mirrors were so little.
The main reason I avoid Apple's download site is that there are seldom free alternatives listed for commercial software. If I know what to Google for, it's generally cheaper just to go to the host website.
Among the free software not listed at Apple.com is MilkyTracker (which competes with GarageBand), Colloquy (a free IRC client), and most of all PySol Fan Club Edition (which contains hundreds of varieties of Solitaire games).
Furthermore you'll likely never see a cross-platform programming library on Apple.com because they want you to be locked in to their operating system and hardware. If you want to download the Mac versions of SDL, SFML, or OpenAL Soft, you'll have to download them from their own sites.
I wish the downloads at Apple.com were as centralized as Aminet.org rather than the other way around.
