Nice biased post Frogboy.

Now obviously the world can't be pefect and have a single audio format, but if I had to chose one it would be WMA. WMA is on more then 500 devices, including DVD players, PVR's and even receivers... with over 4 million units sold, more then twice the number of iPods.
AAC however, only works in the app it comes with, and only on one player ATM, and if you've ever used the iTunes for windows, it is definatly a 1.0 product as 1/2 of my machines can't get past 2 songs on it before it starts stuttering and whatnot.
winsupersite.com is also reporting that HP will have WMA support by mid-year, a very smart decision IMO... so all my rant could be for none
