We have dozens of hi-res unboxing photos of Apple's new iPod shuffle, showing the form-factor change. Similarly to latest-generation iPod nano, Apple has chosen to move away from the shorter case and switch to a taller, more rectangular housing. The company apparently placed the small size at a high priority, integrating a dime-size 73 mAh battery that cuts two hours of playback time from the previous generation. Surface buttons have been removed and replaced with in-line controls on the headphone cord. The system still allows standard headphones to be used, but without any pause or volume controls.
