- -At least 8GB of internal storage, plus SD or SDHC expansion
-Good battery life
-Ability to playback not only MP3 files but FLAC and/or OGG
-Can't be an iPod
But here's the real kicker: it can't have any recording capabilities of any kind. Nor can it have any transmit capabilities. So no WiFi, no microphones, no FM recording, none of that stuff. My first thought was the Sansa series, but they have microphone recording capabilities. All the Cowon mp3 players from JetAudio also have the same problem (plus they do FM and line-in recording). So at this point I'm at a loss. Anyone know of any?
