I just bought my wife a new 7th gen Nano to replace her old, dog-chewed 4th gen. She is complaining to me that there is no hold button. The button that it calls a "hold" button is the same as the iPhone's lock button - it turns the unit's screen off. However, all of the buttons are still easy to hit, and pressing the wrong button can start music in her purse and kill her battery, or pause music during her workout, etc. Is there something I'm missing? Or did Apple decide to ditch the age-old tradition of a hold button on a music player? I say age-old, because in the early 90s my Sony Discman had one... It just seems like common sense!
