This seems very un-Apple. They strive for intuitiveness, simplicity, and elegance. This is the complete opposite of that! Requiring an adapter is about as complex as any MP3 player on the market. And controls on the headphone wires are unsightly and clunky. I would have thought they would have gone the route of the new Nano, and have a shake feature, or something like that. But they changed something for the sake of change.
I am no fan of the shuffle, and it's minimalist approach, but I do appreciate the niche market that it fills, and the simplicity of its function with software, such as iTunes. But this is a step in the wrong direction, even by my sophisticated standards!
What they SHOULD have done was use either a 'shake' style shuffle, in conjunction with being Bluetooth/wireless ONLY! Controls can be on the headset, as are already on Bluetooth headsets.
