Oh man another thead.
1. What do you prefer?? Seems like a personal decision to me. I know I personally do not listen to NFL games on radio or listen to stern. I listen to more baseball on the radio but it wasn't a big pull for me to get XM.
2. Where you want to listen to it? XM has a new things called XM2Go where you can take it anywhere. You can carry it with you as you walk, it also comes with a car kit and a home kit for wherever you want to go.
3. Yup, plug in the headphones.
5. Nope, but I have not really looked at it.
Satilite radio no matter what the company is very worth it IMO.
