Whether you judge your GPS unit by its screen size, the usability of its interface, the comprehensiveness of its maps, or how sexy the British female voice is, there's gotta be something here that pokes your GPS jones right in the ol' touchscreen.
You know what would be cool? If somebody, like, printed out a picture of all the streets and highways and stuff on a GPS, and put those printouts together into a book. Or maybe a big folded-up piece of paper. Anyway, you could keep these printouts in your car and use them to get around when your GPS didn't work. But wait, how would the paper talk to you? Yeah, never mind. Dumb idea.
