Hearsay Man, our dedicated XM spy, points us to his new lust object, the Delphi RoadyXT. As we see from this picture, it is larger than a quarter but it weighs 2.8 ounces and is just .61" deep. This obviously means we're much closer than we were to seeing a truly portable satellite unit.
The RoadyXT will only be about $99, which makes it even better. As OrbitCast points out, the 2-line display is pretty skeeze but a stock and sports ticker adds a bit of flair to an otherwise bland display.
