The other thing I love about apple is they don't treat me like a thief.
I don't have to input license codes and subject myself to product activation.
When I had bought windows PCs in the past, they were littered with crapware, trial software, AOL and other preinstalled nonsense. You'd easily spend 4 hours or more just ridding yourself of the junk.
With apple your macbook is beautifully packaged with each accessory carefully wrapped in its plastic blanket. You boot up in a snappy 10 seconds to a clean desktop with no crapware that you need to delete.
Leopard is a masterpiece from a developer's point of view. WinFS was a failure, but apple added ZFS, DTrace and other goodies that make the value proposition unbeatable.
