Uhm, it's not 'incredibly superior'. Never was really. It was chosen by Apple beause it had the DRM option, nothing to do with sound quality. Nothing. It's more like the difference between HD-DVD and Blu-ray.
from the same wikipedia article linked earlier in this thread, posted as proof of AAC betterness: "However, in terms of whether AAC is better than MP3, the advantages of AAC are not entirely decisive, and the MP3 specification, although antiquated, has proven surprisingly robust in spite of considerable flaws. AAC and HE-AAC are better than MP3 at low bit rates (typically less than 128 kilobits per second)[citation needed]. This is especially true at very low bit rates where the superior stereo coding, pure MDCT, and more optimal transform window sizes leave MP3 unable to compete. However, as bit rate increases, the efficiency of an audio format becomes less important relative to the efficiency of the encoder's implementation, and the intrinsic advantage AAC holds over MP3 no longer dominates audio quality." My 320k max VBR MP3's average about a meg per minute - an average of 128kps (slightly less actually) and sound like Cd's. Unless you listen at 64kbps, or streaming things on the web AAC has no real advantage. AAc was designed to squeeze more into the same 56kpbs modem bandwidth most of us had back in 1997, and to squeeze more audio onto our insanely expensive 500Megabyte drives. Whoop de do. Nintendo is not going to change the market with their new DS. They are just going to look stupid.

What you're completely failing to consider is the fact that CDs are burnt at 128Kbps, so 99.9% of the MP3s out there are at 128Kbps bitrate quality (even if they're ripped at a higher bitrate).
Additionally, any higher than 128Kbps gets difficult to hear the difference. And above 192Kbps is impossible for anybody untrained to hear a difference. So, the lack of an advantage at higher bitrates is pretty negligible.
Lastly, it's not just sound quality that's better. AAC files are also a smaller filesize at the same bitrate - so not only does it at least offer equal quality (and higher, at low bitrates), but it does it while taking less space.
