Apple iPod Touch, fourth generation (photos)

The volume buttons are still located on the left edge of the Touch, though they're divided into two distinct buttons now instead of the single rocker switch design used on the two previous models. We took to the new volume button design without any hiccups, but we were thrown a little by Apple's decision to move the screen sleep/wake button from the left side of the top edge to the right. It's a win for lefties, we suppose, but it took a little adjusting to.
