CJ is right, they're not quite the same things. The GPS display, with an arrow pointing to the destination (I actually prefer to see the distance and direction numbers, not an arrow, but that's just me) is more useful than just seeing it displayed on a map. Both are useful, and having the ability to quickly switch between the two displays would be really nice. Having a satellite photo of the cache location, and the detailed navigation info, on the same device is what lots of people have been looking for, for a long time. Just a little more integration, allowing the logging of the cache, notes, etc into the program would pretty much be the holy grail of caching.
