I voted negative, because it is MP3 format. C'mon Amazon! Donnez moi une break.
Apple doesn't offer files sans DRM at 128, they're all in 256!!
Your iPod can hold the same number of 256kbps Mp3s as 256kbps Mp4s.
Again, at 256, you almost certainly can't hear the difference between the two formats.
That said, we STILL don't know the bitrate of the Amazon files, so we'll have to wait and see. If they're at 192k/s, Apple's got them beat by a lot. If it's 256 or higher though, and at the same price/song, I'm going with Amazon.
AAC could easily be added to any player though, they just choose not to.
That's the way things are though, regardless of whose fault it is.
As someone mentioned earlier, people will be pissed that Apple doesn't offer DRM-free tracks in OGG format too. It can't be helped. Mp3 plays on
almost all portable music players including some types of CD players (Mp3 CD, anyone?). They also play on almost all home DVD players and some factory car stereos (standard!). Thus, if the quality is the same, obviously you want to go with the one that you can use in the most devices.
MP3 has a horrible size/compression ratio than AAC and i can notice a difference between the two except at 320.
You're better than most, then.
Most audiophiles can't tell the difference between 256kbps and
cd quality. (

Regardless of whether or not you "can notice a difference" (not that I necessarily believe you), this hardly makes Mp3 "horrible."
Mp4 is certainly better, but it's really not
significantly better at high bitrates. ['Significant' meaning having any non-theoretical advantage]
If Amazon sells Mp3 at high bitrate at the same cost as iTunes, it
will be a better product (due to its compatibility). Whether or not it's convenient to buy them through Amazon's setup is another question entirely.
This guy had a good point about itunes' mp3 encoder as well:
Anyone who says they can easily tell the difference between mp3 and aac at anything above even 192 is wrong...as long as they are using a good mp3 encoder. All 'audiophiles' (people who really really care about this stuff) admit this unless you are using extremely highend speakers in a great environment. Even then the double blind tests in these conditions say you cant tell. Itunes is known for using a poor mp3 encoder though so its possible that is the problem but even so at a high bitrate you cant tell.
