There are lots of reasons to go Satellite vs iPhone / MP3s etc. A. I can travel across the country, and listen to the exact same channels. Try doing that with FM or even streaming radio via iPhone. I bet you'll lose the cell signal in some parts of the country. B. You get the ease of having the XM / Sirius hardware integrated into your car or your home equipment, fewer things to screw around with when you're driving or just simply want some music. C. Getting music from your iPhone to your radio in the car is done via a crappy FM transmitter or proprietary hardware. What a pain... goes back to B, ease of use. D. If you're chosing MP3s / preset playlists... you miss out on finding new songs / artists that you might like. It drives me crazy when friends of mine have playlists that are always the same artists and never go outside their box because they don't listen to other mediums. That's just my 2 cents.
