Watching Sirius Satellite Radio and XM Radio duke it out is a lot more fun to watch than the HD-DVD vs Blu-ray battle. To be honest, I am a Sirius fan, but the new Sportscaster ($59.99 MSRP) for XM is pretty appealing. (And what a great name!) The product was developed with Advanced Global Technology and is designed to be a personal satellite radio device that can use in your car, at home, in the office, or just slip into your pocket. It plays 160 XM radio channels and comes with a FM transmitter, which is a nice nod to the old school.  I would still like to have some storage for local MP3 playback, like the Sirius S50, but I that just might me.
