The two companies made sportswear and porta-player work as one to update and record the performance of a person who is engaged in any sports activity. After working out, simply connect your iPOD to your computer and it will automatically upload your recorded performance to nike's website wherein you can view your performance and compete with other runners. iTunes Music store will also feature recommended "sports music" that may or may not increase your performance while you work out. Another possible feature of the iPOD that is wirelessly connected to a shoe is changing the tempo of a music depending on the pace of the person. What if I'm listening to Frank Sinatra and start to run as fast as I can?
The idea for me is good except for the tempo feature.
