I think UUID is used because it is better to use UUID to recognize the drives than /dev. For example, if you're trying to have your USB drive automount to /mnt/usb, you'd use something like "/dev/sdb1" in fstab, correct? What if you plug in an external drive? That will be picked up at /dev/sdb, and following that the USB thumbdrive will be picked up as /dev/sdc. The reason for UUIDs is to make it so that the computer can recognize the drives by their device ID rather than the order they were plugged in. I may be wrong though.
