I have a Kenwood head unit in my truck and have been thinking about getting the Sirius system to go with it (Kenwood supports Sirius, not XM). Anyway, I read on the boards a few days ago that Sirius was rumored to be closing up shop (going out of business) so I was concerned for my satellite jam session future.
Whatever the case, I heard today that Sirius has signed a 7-year contract with the NFL for an ungodly sum of money and stock. So, take heart Sirius owners and future purchasers -- it seems that Sirius is staying around for a little while longer.
