Im thinking of buying a hd1, got a good price. But I wonder if it's possible to use the usb-cable that is shipped with hd3 on the nw-hd1 ? I haven't seen it myself, but it's supposed to be smaller than the hd1 cradle + you don't need the power adapter, right ? I'm asking because then you can atleast use the hd1 as small portable hd, without bringing the cradle and the power adapter. anyone know if this works ?
