Trakdot Luggage Tracker

OK, this one violates the premise by being obviously and immediately useful. GlobaTrac introduced a tracking device designed to be thrown in your luggage that lets you know if your bag made it to the same city you did. Trakdot uses cell-phone networks rather than GPS to find its location, which it can text or email to your laptop or cell phone. It's $49.95 plus $8.99 activation and $12.99 annual service fee.
