We're driving for a weekend of golf (and Coronas) weekend, listening to my brother's 20GB iPod for a couple hours when we started talking about what will happen to satellite radio when every car comes equiped with an iPod connection as a standard feature. If it's a snap to plug in your iPod when you drive and have total control over content (music, podcasts, audio books, etc.), why would you pay $15 or so a month for satellite radio? That said, satellite radio does offer tremendous variety and there will be niches where it will thrive (rural communities, cottage owners, travelling salesmen) but how big will the market be if the iPod becomes really car-friendly? I could be badly under-estimating the appeal of satellite-radio and/or over-estimating the appeal of the iPod but I can see the iPod becoming a far more popular on the road tool.
