These are two very different offerings, both of which have been embraced by millions of consumers.

XM is unique because we have hundreds of programmers delivering millions of songs plus live news, live sports and talk directly to subscribers.

Our studies consistently show that long-term durability is a tremendously important factor for consumers.

There is a big capital cost. We have more than 1,000 repeaters across the country, too, to keep the signal strength.

By working with Arlington County, XM now offers drivers in the Washington area a way to get very current, very important and more detailed information very quickly. We hope it becomes a model for other local governments.

We've seen millions of MP3 players sold and millions of satellite radio products sold. Now we're marrying them together and will hopefully create a new market.
