There's a reason more than one company is a good thing. Now, the Sirius/XM provider won't have a whiff of competition. Therefore, they won't have to compete, and you won't get as much for your buck.
Good deal for the two providers; not good for us.
Apparently XM & Sirius' take on that is that their competitors are regular radio stations. But I don't buy that - to me satellite programming is a totally separate service to consumers. Not to mention on-air radio is regulated by the federal government through the FCC. Satellite radio is not.
