If you're a forgetful person, you know that always misplacing your wallet, keys, PDA, or children turns from an endearing foible to an infuriating and expensive curse pretty quickly. Perhaps you could use some help, and your options are pretty limited. You could go to a hypnotist to fix your faults, or you could just get this Mini Reminder to do the remembering for you. The Mini Reminder is a two-part device, with a receiver that clips onto your belt and a transmitter that clips onto whatever valuable you're most worried about misplacing. If you happen to move 10 to 25 feet away (you can set the distance), the gadget will beep or vibrate at you until you go retrieve it. You can also hook up multiple transmitters to one receiver, so you won't be able to leave without your wallet, iPod, and umbrella. Just imagine all the trouble you'll save when it forces you to remember to take, say, your medication with you when you head out on vacation, or your baby with you when you leave the supermarket. The possibilities are endless. The Mini Reminder is $40 and available online now. — Adam Frucci
