Can anybody answer these questions about the new HI-MD players MZ-RH10/MZ-RH910: - Plug'n Play: Will the players pop up in Windows Explorer as an harddisk, without any software installation, when connecting the players to a computer through USB? - SonicStage: is this program NEEDED for transfearing music to HI-MD, or can I use Explorer in Windows to copy & paste MP3 music files, both directions, without restrictions? - AA battery: Is there anywhere a photo of the add-on AA-battery pack, or is there a mp3-play-enabled player which uses AA batteries as standard? Like a new mp3-play-enabled version of MZ-NH600...
