We just discovered this the hard way: The Nike+iPod peripheral that tracks your distance doesn't let you play music on the new nanos. It's a small, surely fixable bug, but it's very annoying on top of the other issues we've had with this generational jump. Whether it's the Cover Flow interface lagging (which has thankfully been fixed), the problems with video out (which Apple is still sort of working out), or various screen issues, we've seen problems at every turn. And ironically, the new, more advanced iPods are impeding their own functionality. [Apple]
