what is ogg?

i've had soo many people tell me that ogg is better than mp3, how? i know ogg is opensource, but as long as the bit rate's the same does it really matter in terms of quality? or does the differnce matter in size ?

I don't have any AAC on my computer and agree that I shouldn't trust the format.
I don't care if iTunes sucks from a "technical point of view". It is the only player that allows me to find one song out of thousands in 4 seconds and it never ever skips.
Is your experience only based on the Windows versions or on what people told you?

First paragraph: FUD. None of this is gonna happen because of the financial interests the companies have in MP3. And serious musicians already own gear, which includes a computer and professional software that includes a licence for MP3.

I agree that open formats are importants. But you know what? You lost the MP3 battle. It is much more important to fight for things that are not hopeless, like against DRM, than to get OGG to prevail.
If you can't get nerds like me to care about OGG, you just can't win, because it means NOBODY cares.
