We'd heard at CES that Slacker Portable wireless PMP was due to be released tomorrow, and now Laptop's gone and confirmed it for us. Slacker's marketing VP says that 2008 is about expanding the Slacker service, with additional products, including some from Logitech, and even Slacker apps for mobile devices. Still, they've got to get those initial $199 4GB and $299 8GB units out the door -- tomorrow is the first day of the rest of your life, Slacker.
