Last week's Let's Rock announcements of new iPods made me want to finally take the plunge and get the Nike+ system so I can rock out with my new Nano and get fit at the same time.

One thing holding me back, though, is Nike's own line of running shoes that you're supposed to purchase to use with Nike+. Since I need a lot of support and am picky about my running shoes, I just thought I'd hack the system and put the Nike+ sensor in my chosen pair of shoes.

But hold up, says Apple — turns out they're filing a patent to make it illegal to put those little sensors in other shoes. I'm deflated. I understand that it's proprietary technology, but I can't tell my feet that! Do you use Nike+?
