If you are anything like me, remembering where you parked your car in a crowded lot requires entirely too much brainpower. The Ecco GPS can help you with that problem in a keychain-sized unit.
Keep in mind that the Ecco does not work like a traditional GPS—instead of finding new locations, it is designed to lead you back to one of three stored locations. So, if you are a Disney World and you want to keep tabs on where you parked, your location can be stored onto the device and used later to lead you back.
The Ecco only has an effective range of 9999 miles and an accuracy of 32 feet, but it could come in handy to fill in the gaps for people who have no plans to buy a GPS-enabled phone. [CuteBitz]
