A feature, which in my opinion should be required, is that the player show up as a mass storage device. So you can manage the files on it as if it was just a USB drive. As opposed to requiring proprietary software to copy media files to the player. That way if you have any other file you need to transport, you just make a "Junk" folder or what ever and store your stuff there.
I agree but everything I’ve read recently is blending together, can you recommend one that operates like that. I’ve seen a lot of car audio that will sync up with an iPod using the same interface but haven’t noticed if there is anything out there that would simply work as an external hard drive or flash drive.
