It looks like Apple is teaming up with Nike to turn your iPod Nano into a calorie calculating machine. That’s right, here is how it works:
Any mere pedometer can show you stats while you run. But thanks to the Nike+iPod sensor and receiver, iPod nano also transfers your workout data to the Internet as soon as you sync. Connect your iPod, and iTunes takes over, automatically syncing all your run data and sending it to nikeplus.com
If you are an exercise nut and have a Nano then go check this out, otherwise the upcoming iTunes 6.0.5 upgrade probably won’t mean much to you.
