Both SIRI and XMSR are highly specultive stocks. You are no supposed to have more than 5% of your portfolio in any single stock that may zero itself in no time.For that reason only, I'd sell them ASAP.Put your money in mutual fund (subscribt to champion funds for a good selection).By the way, my friend has a phone with internet connection on it and Microsoft Mobile 5. He can hear any station (like onee from his country of origin) for free. I can bet in 5 years this will be the much bigger hit than satelite radion. Maybe XM will provide internet radtio for reduced fee, but don't expect satelite radio to do much better than satelite phone.
