i have sirius in my vehicles and must say i've been spoiled and can't see going back to standard airwaves again! i've had it for nearly 2 years now and can't recall playing a single cd since its installation (enter the "audio express" home of the $1 install..." plug here). it also comes with dish tv so i don't need a home unit and not even sure if sirius has a home system anyway. sirius bought howard stern and he started in january but it's still the same show, just without the bleeps...yet they supposedly signed him for half a billion bucks??? holy shit...
