I have had Dishnetwork since 1998. They had growing pains also. The more I show XM to people in my GMC Envoy. The more people sign up. XM has made me want to drive for travel again. It will grow.
I take monthly trips from Western NY to Boston, and frequent trips from WNY to Detroit, Washington DC, NYC, Toronto, etc.
XM is awesome for 6 hours in the car. In some parts of Pennsylvania and Ohio, there's only the "3 C's" to listen to... Christian, Country, or Crap.

Same here with my Buick LeSabre. Nice to drive cross country and never lose a station.
