I love my XM radio. Wouldn't leave home without it. (But I own stock in Sirius, mainly because I was too late to get in on XM).
I have had Sirius for about 4 months and love it. I'm in my car from 3-8 hours a day and have Fox News, cnn, bbc, etc.,local weather/traffic and any kind of music you want to hear. Now I can leave the house in the morning when something big is happening in the news and pick it up in the car without missing anything. I can't get Rush, but I can catch Laura Ingraham on delay on the TalkRight channel, as well as other talk radio shows. I can tune to Rush on my local A.M. station, so all is right with the world. (excuse the pun) I highly recommend it.
