Obviously, you are wrong and make stupid assumptions about people you do not know... And can't seem to handle an opposing opinion very gracefully. 🙂
I'm a running nut. I use a 5th gen nano currently, which I carry in my hand so that I can easily control it as needed without looking at it very much, or making any unnecessary movement that disrupts my running motion, just to reach for it clipped on my clothes somewhere. I can hear the ongoing Nike+iPod voice tell me the "statistics" for my run, pause/resume workout, skip song, change volume, etc. without any distractions. I would go nuts if I had to look down at where my iPod was clipped to do basic things that I do a dozen time during a run. I would probably trip over something and get hurt.
Also, clipping it to sweaty clothes will cause moisture damage over time, and shorten the iPod's life.
I would be able to use the 7th gen nano mostly the same way. It has a touch screen, but there are buttons along the side for controlling functions, usable by feel alone.
