as a sony owner, i'dd like to agree with you all that atrac is entirely pointless, and the only faults with their players are that, and sonicstage
but the battery life on my nw-hd3 is quoted at 30hrs, but that's only for 64kbps atrac, if you use 256kbps mp3 or higher, you only get about 20 hours of battery, so the 50hrs would probably be reaslistically around 30-35, i know it still kicks the ipods arse, but it's not quite as fantastic as quoted
