One of the reason I wanted an iPhone was because I thought it would be good in combination with Nike+ (which I was sure would get an iPhone release). However, now that I got my iPhone, and played around with it, I realize that the device is simply too big to comfortably run around with. I'm not a small guy, about 6'5" and not exactly skinny, but I just can't see myself running around with the iPhone on my arm. Obviously the same goes for this program - which I am sure is well made, but the iPhone is just not for running in my opinion.
I'll just wait for the new iPod nano and purchase it especially as a running device.
Nike Super plus ftw... I thikn we'll be hearing more isnce they've teamed up with 24 hour Fitness - why wouldn't they or Apple want to get an app going? Couldn't the iPhone 3G also do a BT footpod if one were to come out? Still waiting about news on Ant + and HR monitors. If only they could - it'd be awesome. Till then, the Forerunner 405 seems to be winning out on useability.
