My son gave me this for father's day, and so far I'm enjoying the baseball coverage. The music selection is nothing special, the comedy is mediocre at best, and the "old time radio" is kind of fun. Their blues channel isn't great, but its not bad either, and a decent thing to have on when I don't want to think too much about selection.

The strength, for me, is the MLB coverage which is excellent, and takes me back to my childhood when baseball always seemed to be on the radio on the weekend. Personally, if I can't be at the game, I prefer it on radio to television.

They know they have the system and will not work with anyone. I've had problems tring to get both my radios on the same billing cycle and getting a radio replaced and it's always "to bad so sad" for me

Love my XM. O+A and MLB and great music.

Had it becuase it came with the car but dropped it after the free year was up. Not enough content, played the same songs in rotation. Lost NASCAR and has O&A, what more can I say.

XM stinks! Listen to "Bluesville" and compare to "Sirius Blues" Sirius wins hands down!

Great technology, great programming. When the Inno comes out, XM will be untouchable.

just want to say i cannot tell you how much i enjoy xm i love it so much i got it for 3 of my family members it is really unbelievable 169 /170/ 33

The only downside is their customer service, took me 3 times to deactivate an old radio and properly activate a new radio.

I bought Sirius this year. I was skeptical at first having to pay for radio but boy was it worth it. I was tired of having only one channel in my area with music that I liked and tired of waiting for the commericals to end. I now love Sirius and haven't listend to FM since. No commercials on any of the music channels, NFL, NHL, NBA, and NASCAR in 2007. Dang...I sound like a commercial. The only downside to Sirius is deciding what to listen to. For $12 bucks a month, well worth it. I bought Sirius for the coming of Howard Stern at the end of this year. I still would subscribe anyway even if he wasn't coming. Terrestrial Radio, in my opinion, will be obsolete in a couple of years.

I had XM befor i got Sirius, I was disatissfied with the reception, customer service, and channel selection. I am with Sirius now and am much happier.

i have listened to both for over 12 months now. XM wins everytime.If you want great comedy and quality talk shows get XM, if you want cheesy DJ's that love to hear their own voices Get Sirius Radio, but aviod their stocks.

Absolutely great! Great programming, great service, and less expensive than Sirius. Have one in the house (Ski-Fi) and one in the car. Highly recommend.

Why listen to commercials when there are none on Sirius?
