Again, what is the content?

I can state without reservation that you can get content from XM you
can't get any other place. 65 or so channels of commercial free music
that simply are not available anywhere else. A lot of which you
couldn't walk into your local music store and buy if you wanted to.

In addition, you can't get the talk or sports or news content from any
other source while you're driving down the highway.

This is just closed-mindedness. It'll cost you $100 to try it for 3
months. If you don't like it sell the receiver and dockers on ebay and
get your money back. Geez. Don't be a tightwad.
