Largely irrelevant. Full-duplex at GigE speeds matters only for servers for the most part, and those aren't the machines that will be using USB NICs.

Nearly everyone with an Apple notebook is going to be limited by their internet connection (5-30mbit/sec for most), not by the ~250mbits/sec Real-Life performance of a USB2 NIC.
