How do you like that the controls are included as part of the earphones? What are the plusses and negatives?
I've read several reviews saying that the 4th generation shuffle stops working after the user took it to the gym for a few light to moderate workouts (presumably it couldn't take the sweat). Does anyone have any experience with this? My main use for my iPod is for pretty intense workouts so I need to know that it will work!
