As soon as I saw this the first thing that popped into my mind was "Cool I can have personal theme music!" Apparently Nike will be selling special shoes that have a sender sensor in the insole that will transmit information about your workout to a receiver that fits into an iPod Nano. This will let you load up you Nano with music from iTunes that will match you workout. Now, I suppose you could just wear the sensor shoes around during your normal work day, this way the music you load becomes your personal theme music. How cool is that? Just like Peter Griffin in that episode of Family Guy where he had three wishes. I understand that there will be a ‘power song’ selection that will let you have your chase music for running across a street or your sneaking around music for using your 733t ninja stealth to grab that last cruller from the office kitchen.
