I've been test driving the XM radio service(with the PCR module) and have noticed several things: 1. The "free" preview channels, 5 total, change randomely every 4-5 hours. No big deal there except they keep kicking me back to the preview channel after the first week of previewing. Sometimes takes 6 or 7 clicks to get the interface to change to the desired channel. 2. The quality is something that is at the very least, worse than radio. Adding on top of that it sounds as if they are using MP3's to play the music. The music has a compressed sound to it and the highs sound EXACTLY like MP3s. 3. The wosrt one is that they seem to be giving some channels better bandwidth than others. Example - listeing to John Mayer on one channel sounds better than another channel. And this was VERY obvious. 4. You MUST have a window with a southern view to get signal. And there can be no obstruction in the way of the antenna. 5. Extension cables are WAY too expensive. $45 - the amount I payed for the entire PCR set with receiver, antenna(20-25 feet long), software, and a slew of cables. If anyone has any cheaper ideas I'm all ears. Still undecided on the whole thing due to these issues. The one redeeming quality is their variety of music they play. It is unbeleivable the amount of new music I have been exposed to and as a result I have bought more CDs in the past week or 2 than I have over the past 2 years listening to CLEAR CHANNEL - Hey RIAA do YOU GET THE POINT YET!!! I'm sure they don't(they should hire some chimps as they one probably start seeing a profit). It's amazing where your money will go when there is something your INTERESTED in spending you money on. Just some observations.
