You can carry it in your pocket

Tom Tom One 3rd Edition is a fairly basic and relatively low-priced GPS. It claims to be the #1 selling GPS worldwide, and got good reviews from Consumer Reports, both of which played a role in me choosing it (along with price). The unit is small - about 2 1/2 by 3 inches, and less than 1 inch thick - and lightweight, so it's easy to put in your pocket.

I am very happy with the TomTom ONE 3rd Edition Car GPS Receiver, just the battery life isn’t what it should be. But it is expected since it has a very bright LCD and it is in colour so it uses and needs a lot of power. A fully charged battery will last anywhere from 2 and a half to 3 and a half hours for me. It takes about an hour or so to fully charge, which is good.

This is a great little device that would make a nice gift, even for the non directionally-challenged. It is small, relatively light, and is full of functions that could reduce reliance on several other gadgets, and even help save the lives of, both, loved ones, and total strangers. It doesn't include whiz-bang functions like adding blue-tooth speakers for your phone, or display weather, but it also isn't chunky (like my friend's Garmin that has those functions). Highly recommended!
