I'm going to be getting an external enclosure for using an IDE hard drive on 3 diff computers. All 3 of these have both USB 2.0, and IEEE1394 ports available. I'm trying to decide between the model with the USB 2.0 connection, or the Firewire connection. What would be any reasons for going with the USB 2.0 interface, when Firewire is faster? The only thing that comes to me is that one of the computers has front USB ports, so it would be a little easier to connect not having to reach around to the back, but that seems pretty damn minor compared to the transfer rate. Obviously I'm leaning towards the Firewire, but I want to make sure I'm not overlooking anything.
