Did Nike come out with this in 2006? That's when I remember first using it, but haven't touched it since '07.

Honestly, I always felt the foot sensor was inaccurate. Have you done 4 laps on a track to see if it logs 1 mile fairly precisely? It would be interesting to see. I think Polar and Garmin have some better, more serious, less social network like running watches and sensors, that have programs which provide detailed analysis of pace, HR, distance etc..., granted they're more expensive.

In terms of needing Nike + for motivation, I think the thought of not wanting to let down the men next you and yourself in training & eventually life & death situations is more motivating than anything else.

Let me know how accurate it is, I'm sure it's gotten better. Good luck with the running.
