Unfortunately, my iPod nano did not survive a wash cycle in the pocket of my shorts, so that has been out of action for over a year now. Sadly, Apple does not provide any warrantee or guarantee for "water damage".
The upside is that I much prefer my Garmin to the iPod & Nike tracker anyway!
I don't have to worry about earphones, I can easily check the distance any time, and I can pause it and restart it with the touch of a button. The GPS is accurate, and because I can also view my runs on google maps, I now pretty much know exactly where each kilometre marker is on my regular routes.
Highly recommended for walkers, runners, and cyclists. I chose the smaller of the GPS watches available because I wanted the simplest one. It comes in several colour choices: pink, green, and black. I decided I needed a break from pink and opted for my favourite colour: green.
