...or should I rather say that the portable clie docking cable is a perfect match. At one end there is the connector for the clie (plus recharging cord) and at the other end of the cable is a USB connection.
and I wonder if the Gigavault would be charged from the clie since it runs off a USB port??
Sure does, but think of the possiblities for a driver that could access a portable drive (doesn't have to be Gigavault) with a USB cable, or by extension bluetooth.
Conversely, if Apple were to release a giga 'iPoDA' I would buy it in a second..
