No OGG though, but that was too much to hope for.
Another example of when 'free' is more expensive. Ogg Vorbis is computationally much more expensive and less trivial than MP3. Also, there are fewer chips out there that do it in hardware.
Unless something has changed, Vorbis is computationally a little cheaper to decode, but requires more working memory because you have to keep updating the probability model as you go along. MDCT against FFT on the computation, if I remember rightly. There are fewer chips doing it yet, though, which is the biggest reason it's not seen in more places.
