hmmm...good point...
but how much market share do you think it will need before mp3 device manufacturers decide to start using it in players?
have any announced any plans to use it yet?
I also think it would make more sense for them to firewire due to the fact there are a large number (ext drives, camcorders, etc.) that already are using it. It's seems that they should be smart and do so, as well.
