This player hits all the high spots for features. They've also made the OS and Firmware open source, though it appears they've had to take down the source because some of their vendors claim they've released proprietary information. It sounds like they'll work to get past that roadblock. And they released the schematics.
So we can look forward to some Neuros hacking. Perhaps even a sane OS that lets you drag mp3s and such onto the disk and play them without going through a hokey file copying utility.
