PC World have published a review of the Sony NWZ-A818 Walkman media player. 'The NWZ-A818 has a 2-inch QVGA (240-by-320-pixel) TFT color display, comes in either a black or a silver case, and weighs 2 ounces. Supporting .aac, .mp3, .wav, and .wma files, the unit can play music for about 30 hours on a full charge. Instead of using its own software for advanced management of music and playlists, the NWZ-A818 syncs perfectly with Windows Media Player 11 (a copy of the program is included with the player). More-advanced users will enjoy the players' ability to accept music and videos introduced by dragging and dropping.
Though Sony bundles a brief instruction manual with the NWZ-A818, navigating the A818 with the four-way main control button and dedicated 'option' and 'back' buttons is intuitive. The menu interface is straightforward and responsive, too. With just one hand, you can easily shuffle songs and search for photos or videos. However, putting the hold button on the back of the player wasn't the most inspired design decision.'
