I much prefer the GPS that just shows where you are and points to waypoints with time and distance. It also serves as a compass. Combine that with a geo map of the area you are in (maps are much larger than the screen on a GPS so much more useable).
I'd avoid the cell phone GPS things as in the deep woods you are apt to run out of cell phone coverage.
BTW, don't leave your compass at home since you may lose the GPS or drop it in a well or run out of batteries, etc. Compass and map is adequate if you learn how to use them. Garmin is without doubt the best GPS system.
