a USB key:
a device that enables a software function to occur only when the device is onncected through USB
Its quite old school, serial keys have been around for a long time. Most people dropped the key in USB, cause there are so many more clean ways to do this w/o a device.
Thats great and all but has nothing to do with an internal wireless card.Not only that but where on Apples site does it show or say "includes USB key/device" ??
I call bunk on this rumor.
