Its certainly not necessary - a good paper map/atlas is really more important. A GPS can often lead people to "turn their brain off" and get into trouble by blindly follow the computer. That said, as a secondary tool, it can be a very nice addition to a trip. The biggest feature I like is that it can tell you about restaurant/gas/lodging options.
