We’ve been big fans of Slacker since we saw it earlier this year at CES. Now, we were big fans of the Slacker Internet radio service, but that meant you had to keep Slacker in your browser. With the Slacker G2, all that Internet radio goodness is now portable. So, why the Slacker G2 over a regular MP3 player? Well, first off, the owner doesn’t have to pay for the music. You don’t even have to use a computer to transfer music to the device, as that can all be done with the devices itself. It connects to the free Slacker service over Wi-Fi, and will update itself with music whenever it has a connection. The 4 GB Slacker G2 supports 25 stations, and retails for $199.99. You can pick one up at Amazon.
