I love Sirius! We had both for about a year, one came with our car the other we received as a gift. We tore the XM out of the car and bought another Sirius receiver (two more as a matter of fact). It seems like Sirius technology is far ahead of XM. NASCAR is moving to Sirius and it has the NFL which was a huge selling point for us. As far XM not paying one person a huge amount of money, they just paid Oprah a ton of cash for a show she will do 30 minutes once a week. They are paying her way more than Stern got paid if you work it out by air time.
