Just from looking at their websites (
Siruis and
XM Radio) I have gathered the following. XM costs $9.99 per month and Sirius costs $12.95 per month (when you sign up for month by months plans). Neither supplier censors their channels and both offer portable versions of their players to be used both in the car and in the home. XM has 68 channels and Sirius has over 120 channels. Can't tell you about the qaulity though (although on XM's site you can listen to a sample of each channel). Both offer small square black box style antennas (XM has a micro antenna which is pretty small); perhaps an aftermarket company supplies a hidden antenna that is compatable with either of these services?
Also, from
RadioDailyNews.com:
"As I am writing these words on my computer, I am listening to the "60’s Vibrations" on Sirius Channel 6 via the Internet, through my stereo computer speakers. It’s a "bonus" at no extra cost for Sirius subscribers. You’re provided with a username and password and can listen to the same music channels that you hear on your Sirius radio receiver through the Internet via your computer’s soundcard -- at no extra cost.
XM has introduced a similar method of listening to satellite radio on computers with their XMPCR unit. It’s $69 and requires a subscription fee of $9.99 if you’re not already a subscriber or just $6.99 with the XM "Family Plan.""
