The Slacker Portable Player is not your average MP3 player. Rather than just providing the space for you to transfer your digital music (and sometimes video) collection, this device offers an integrated music-listening experience courtesy of the Slacker Web Player. Although the service itself is provided for free, the Portable Player is not a cheap device in the scheme of things, running well above the average price for most music players (the 2GB, 4GB, and 8GB models run $199.99, $249.99, and $299.99, respectively). But this player offers something the others don't: freedom from being tethered to your desk, creating playlists, and transferring them through a cable connection. The Slacker's Wi-Fi allows on-the-fly updating of DJ-created stations...without making you pay a monthly service charge.
