PlusMinus was created for running geeks who are paranoid about all their running socks being in one online laundry basket.

As you may know, all running data is stored on the Nano, and synced only with Nike's website. There are no local copies saved on the computer.

This worries geeks like me - what happens if one day my Nano goes wonky and the Nike website is down for some reason? Where are all my runs??? Argh!! I must not have run all the runs that I have run!!!??!? *breathe*
