For some strange reason, Nokia does not provide an active (powered) car holder for the N73. Since the N73 is suitable for GPS applications, we obviously need a (powered) car holder.
Fortunately, Brodit has now launched both an active and passive car holder for the N73. Look at:

And please Nokia, as the N73 meets all my PDA needs and now has replaced my Pocket PC, could you create a nice powered desk cradle . . . ?
