Clarify please?
I am a subscriber to Slacker and Sirius. I use Slacker through my cell phone (AT&T) in my truck (ford) which has the sync system. I used to use Sirius, but after trying Slacker, the sound quality is much better than satellite radio. My CTS which wifey mostly drives has the subscription to Sirius. She's less particular about the sound quality so we keep it in that car. Slacker offers an offline back to your device which I use frequently on plane flights. You can also tailor the algorithm to your taste. I have 0 commercials and unlimited skips. Listened to Sirius lately? It's almost like FM radio with all the commercials, and Howard Stern cool, but not worth $15.00 a month.
