The most noticeable thing about the second-gen iPod touch is just how thin it feels in your hand. The tapered edges make it feel like last year's iPod Nano, and it isn't as heavy or dense feeling as the 1g iPod touch. As Jobs stated in the keynote, the built-in speaker really is for casual listening, as it's not loud enough to cut through the crowds here. But when held to the ear, it sounds decent enough for what it is.
