I just started using it this morning. DNouncer Duane if anyone wants to add me. I used the Nike+ GPS app, but I didn't realize I hadn't actually started yet until I was almost back home.
I haven't run regularly in years, so as I try to get back into it, I'll be pretty casual. Maybe only a mile or so per day at first, although I'm going to try to shoot for every day or close to it.
Oh, and by the way, how well does this work on an elliptical? I have one in my house I like to jump on (far too) occasionally.
