Summary: I was given 2 pairs of Nike+ shoes as a gift and I naturally became intrigued over the system. Eventually my old ipod photo died and I opted for the iTouch. I was excited to see the Nike+ software pre-loaded so all I needed was the chip. I love to run and I average about 15-20 miles a week. I enjoyed tracking my runs and getting time/mileage updates at the press of a button and when nearing the end of a run. I used the system when running outside or on treadmills.
Summary: I love the Nike+ concept, but the sensor life issue is really driving me nuts. I am on the third sensor this year. They seem to last me about 3-4 months and then they die. I run 6 days a week and would have thought that this product would last a bit longer. Hey apple - either refine the product or drop the price of a replacement-$19 plus shipping is a little much.
