If you’re as organizationally-challenged as me, misplaced keys and cell phones are a weekly occurrence. Lucky for us, they’ve come up with gizmos that will page your lost keys for you, and a website that will make your missing cell phone ring so you can track it. Sure, if you have a landline or a roommate, you could just use another phone to call yourself—but if you don’t have an extra phone handy, this is a big timesaver. Or, as one astute co-worker pointed out, you could also call yourself from your laptop during a staff meeting and then duck out early saying, “Sorry guys, this is important—I have to take it.”
