Hi, I'm looking for a HD based MP3 player that is recognized by win2k/XP as USB mass storage without the need to install any drivers so that I could use it to transport files to/form any win2k/XP PC. As far as I read the reviews online, the iRiver iHP does not need any drivers, the Dell DJ and Creative Zen still need driver installation, and the Rio Karma requires its own software. I also heard that the iPod does not require any driver. Are those assumptions correct? Any suggestions is appreciated.
