i know this isn't really in keeping with the firmware update, but i had a look at my friends MZ-NH1 the other day, and of particular interest to me was the usb connection cable. the cable offers connectivity to a pc and power supply (as far as i know), whilst my NW-HD1 needs to be placed in a usb cradle for both. i had a good look at the cable and port on the player, and it looked identical to the port on my nw-hd1, and the plug built into the cradle. has anybody tried the mznh1 cable on the nwhd1, or heard anything about this? if not, do you think it's likely to work, or am i venturing into dangerous territory?
