Apple Computer said that though it missed its originally planned October launch date for its second-generation iPod shuffle, it will release the product on Nov. 3. At half the size and weight of the original iPod shuffle, the 1GB, aluminum-bodied device is the smallest iPod Apple offers. It doesn’t have a screen for viewing content, but it does include a clip for attaching to belts or other pieces of clothing, as well as an increase in battery life to 12 hours.
