Well, that is the reason for the "cloud". You just buy a new pair (if you don't carry a spare set already), plug in your ID/PW and pick up where you left off. The scarier part is what happens when Wireless/Cell service cuts out and suddenly everyone freezes in the streets. We already RELY far too much on technology. It's okay to AID us in tasks, but when we forget how to read a map due to GPS' or forget how to hand-write vs texting, or even lose access to our appointments calendar due to a lapse in communication, we're all in a serious mess.
