As some people need these handheld gizmos for everything that they need while on the damn road, a prime feature they look for in such devices is its
GPS functions. Of course, you would need separate hardware to go with either your handheld computer or your PDA. With this function, you could now navigate your way through those damn tricky streets as if you were playing a game on Xbox. But, after I tried one of those so-called high-function GPS gizmos, losing my way seemed to be what I do best when it comes to navigating through busy streets.
