I have XM; the woman has Sirius. Thus, I'm familiar with both.

Last question(s) first: The package will come with your receiver and car antenna. You just need to buy a boombox or stereo adapter for your home or office. (Note--make sure you get the boombox for the specific model of receiver you purchase, as they vary).

As to content, I like XM because of the MLB play-by-play. The country music selection on XM is also infinitely better. Sirius has the NFL package, however, so that's big for some people. Also, the Sirius interface seems to be a little more intuitive.

My wife and I both have Sirius. We love it. If you have a fairly recent automobile stereo, odds are it is SAT radio equipped that way once you get it connected you just listen and operate the radio from your car stereo. If your car is not already adapted then you will need a in Car device that will play through your car speakers (usually what you get when you buy). Most of these devices can be taken out of the car and played in the office/home w/headphones or accompaning speakers. I listen to Sirius through the internet. You get the internet content when you pay for the regular content. XM and Sirius both have tons of content, more than you will ever need, however I do enjoy catching football games on Sunday's when I'm out.

Please note that not all content is available online, at least not with XM. Only music and XM original programming is online. That means that sports and news are not online.

I love XM. I have one that I can play at home and easily transfer to the car. It is XM2Go, but I am sure there are better ones out there now. ACC sports and MLB are both on XM. Between the sports and comedy I rarely use it for music.

I know nothing about satellite radio, but I eschew the local radio when I have access to an internet connection and listen to British pop radio instead. You probably wouldn't like that specific station, but I think online radio generally is A Good Thing

I have XM Roady2 and I bought the home kit that has a power adapter, antenna, and base station. I hook it into my stereo at home. You could also route it through your PC to the speakers. I have no desire to listen to Howard Stern, so XM works great for me. I listen to channels 46 (Top Tracks) and 49 (Big Tracks) most frequently. I also listen to the uncesnored comedy on 150 and the Red Sox games.

Oh and you get XM on the Internet for free when you sign up.
