Apple revealed its updated line of iPods today, which includes reworked versions of all but the iPod Classic model. The iPod Touch now features many of the same elements of the iPhone 4, including the Retina display, FaceTime, 720p video recording, and the powerful A4 processor. The Nano, meanwhile, took a bigger leap forward by adding a 1.5-inch multi-touch display to a redesigned body that’s even smaller than the last generation. The Shuffle took a different approach than the Touch or Nano by reverting back to a design similar to the square second generation, which featured buttons. Apple must have received some complaints about the last-generation Shuffle, which was stripped of buttons and forced users to use the headphone remote to control the device.
