First updating the software basically reformats the thing, wiping thousands of miles of running data which can't be reloaded from the nikeplus site. (So it's there why?) Then I fall for the ol' leaving-workout-going trick again, because unless you yank the iPod from its opaque sleeve and make sure it's stopped, you can't rely on a voice confirmation that's not always available. So my time—bad enough as it is, figuring out the antiquated treadmill at LA Fitness—includes a lovely stroll out to the parking lot.
