I would appreciate suggestions and advices from anyone who has experience with the Canon M80,Epson P4000 or P5000 and the Jobo Giga Vu Pro Evolution.I am thinking of buying one which I'll use for storing raw files,listening to mp3 files but not watching video files.So Still picture quality,sound quality and battery life are important,but not video quality.Any suggestions will be very much appreciated.Thanks in advance.

I presume you're already read our reviews of the Epson P-5000 and P-4000?
