Like before, get an iPod. Firewire runs at 400 Mbps and USB 2.0 runs at 480 Mbps. You may think the usb connection would be faster right, actually its generally slower. Firewire firmware and hardware are designed to be run at a maximum speed all the time no matter what is connected, hence thats while apple uses firewire for its accessories. USB was designed to well, umm, run, and thats about it. Yes it is possible to reach 480, but it may only happen once in your life. USB firmware and hardware is only told to transfer the files, a speed is not specified, so it will transfer the files at a speed which suites the computer or how it sees fit. So firewire will ultimitly go faster. If you want to hook up your Ipod to your car, there is the previous options listed, like iTrip. Or so decks have a mini jack in on the front, so just glup a 1/8" mini jack cord into your pod and the deck. Others will have the old RCA ports on the back, so again just run the cable through. You can get em at radioshack. As for the other functions, there are only slightly similar to a pda. My tungsten works much better than the ipod fuctions do. It can play mp3's, but i am limited to buying a 1 gig card, and well you said pda batteries actually last more than a couple of hours anyway?
