I wouldn't worry about it too much. To take the example to the extreme
the iPod has firewire which is much faster then USB 2.0 but you only
really ever do huge upload/downloads once or twice, making that feature
fairly minor. When you do have to do a large transfer, just set it up
to go overnight. A usable interface is much more important.
I disagree with the point that firewire is quicker than USB2.0.
I am afraid it is not quicker, see table below for differences in speed between different protocols

Note 1394b is not that common yet!
