The lossless world is a jungle of different formats (flac, ape, shn, wv, etc) and there is no single format that is the standard (like mp3). I think it's likely that Apple's original plan was to go with MPEG-4 SLS 'Scalable Lossless Coding' which is fully backwards compatible with AAC, but as that format took years to complete (it still isn't finalized) and its closest rivals such as MS and Real all made their own codecs, they just decided to make their own format that they could have full control over and put in their MPEG4 container (.m4a). This way they can optimize it for high performance on the iPod and AE from the ground up and don't worry about steep licensing fees.

. I believe Apple made their own lossless codec (or at least I've heard this from others) because the alternatives did not fit their needs.. specifically FLAC was too CPU-intensive to decode in real-time on the iPods (which is probably not true of the latest models, which apparently include more powerful CPUs than previous ones).
