I've got both Sirius and XM receivers, and neither of them are hooked up. Between my iPod and my internet radios, I have no need of them. The only thing I truly enjoyed on XM was the comedy channel, and by the end of my subscription it seemed I'd heard everything they had to offer.

I can see where satellite radio would come in handy if you frequently drive long distances, but for me it would have been vanity to keep paying for something that provides me no value.
