PopSci Gets Grubby Paws All Over Upcoming XMp3 Satellite Radio PlayerAll we have is a blurb in Popular Science magazine this afternoon, but it would appear there's a first look of sorts going down today with the XMp3. The portable device is an XM Radio player that can record up to five satellite stations at once. "Other portable players save only one channel," PopSci notes, "but the XMp3 can decode five incoming streams to snag multiple songs whether it's in the dock or in your pocket." That's it for now. Expect more soon or whenever XM decides to give up more info. [Orbitcast]
