I know it came out a while ago, perhaps I am one of the last few to try it. But today as I used it for the first time this cool little Nike+ gizmo, rocked my world. I used to run quite a bit, but unfortunately have gotten out of the habit. This is exactly what I needed to get back into the groove. If you don't know how it works or want to see some motivating ads watch this, this, or this. I cannot believe I waited this long to try it, can't beat 29 bucks for a personal trainer + motivator in your ears.
