"BRANDON KARON: The MacBook Air comes with only one USB 2.0 port which is typically enough if you're on the road a lot, one USB port's fine. Now, for instance, it doesn't have a built-in CD drive, so what Apple created was a SuperDrive that plugs into that USB port. This is it right here, this is the USB SuperDrive. This is for CDs, DVDs, you can burn CDs, you can burn DVDs with it and it's pretty cool and you can put it in right here. Close the machine. Right here is a USB port. All you gotta do-- plug it in like any other USB device, right like that. This will also work with USB JumpDriver Flash drives. It will also work with Apple's Ethernet adapter, in case you go to a hotel room for instance and it has free internet access, but not wireless. You can take the same USB, plug it in. There's your Ethernet cable and it's a normal USB port, so you can use it with any other type of USB device. And there's the USB port on the MacBook Air."
