What's the best satellite radio service?

If you haven't been living under a rock, you've heard the ads for both XM Radio and Sirius Satellite Radio and, perhaps, wondered how the two really compare and which is a better choice for you. A colleague of mine is a big fan of both (yes, he subscribes to both each month) and wrote a helpful tutorial on just this topic, something that is bound to help you make this decision. It's the perfect way to spend that new Christmas gift certificate from Circuit City or Best Buy, isn't it?
