While XM is already offering its customers live feeds on-the-go through the well-received Pioneer Inno and Samsung Helix, rival Sirius has been rather slow to the starting gate in this department, as its flagship S50 portable only plays back content that was recorded while it was docked. Now, however, it looks like Sirius is finally on the verge of releasing its first DAP with built-in satellite receiver, and Tech Effect even managed to snap a picture of the device when CEO Mel Karmazin briefly flashed it during his keynote at this week's Convergence 2.0 conference. Unfortunately Mel only broke out the chunky-looking player to illustrate a point he was making about the iPod ("I wish it didn't exist," he said, probably only half-jokingly), so all that's known about this unit is its size and the fact that it sports a headphone jack. Still, Mel promises that he'll have the product in stores by the end of the summer, and since it's reportedly in the midst of beta testing, we're expecting to see some leaked specs and photos sooner rather than later -- much sooner if any of you testers would be so kind as to drop us a line.
