| Review Summary | The Sony NWZ-A720 is the best-sounding, best-looking Walkman series yet, and the inclusion of premium earphones adds real value. | The iPod Touch is a beautiful product, inside and out, but prepare yourself for sticker shock. | The iPod Touch is a beautiful product, inside and out, but prepare yourself for sticker shock. | The shape may have changed, but Apple's relentless attention to detail remains. The third generation of the iPod Nano provides loads of entertainment for a down-to-earth price. | The iPod Touch is a beautiful product, inside and out, but prepare yourself for sticker shock. |
