What are people's thoughts on using GPS on BGRs?

Obviously taking one is a good safety backup in case of injury, but what about using it for navigation when the clag's down?

At the weekend I used one for the first time on leg 3, cloud wasn't too bad really until 700m, and though map and compass were turned to first, it did provide a very useful reassuring aid.

Clearly it's no substitute for proper recce-ing (I've done most of the route now in very poor visbility), but it certainly makes life easier, and the less to worry on the day the better!

I just can't help but feel it's cheating, by reducing the mountain skill required to solely keeping moving...
