Went to Best Buy today and got downloaded on the satellite radio systems. Basically XM vs. Sirius. I'd love to give the nod to GM (Delphi), but after the full product demo and talking to the sales folks, I'm going with Sirius. They're running a deal right now. Portable head unit with car and home adapter + antenna and all cables, $149 installed. Plus through January 04' Sirius has a LIFETIME SUBSCRIPTION rate of only $399. Unlimited commercial free music for life in the car or at home. Ok I'm in.
