ever since I moved to Houston I found one thing: the rock stations here SUCK! I can only find one station that's dedicated to rock but even still they can play some really bad songs at times...I thought there would be more stations here but I was way off...so I was pondering the possibility of getting satelite radio...but I don't know what is better...xm or sirius...so I ask you guys...do any of you have it? and if so or heard it then how is it? is the quality good? how expensive is it? I was looking at some of the receivers and I'm looking for one that can connect to my car and computer...if it could work like a portable walkman or something then that'd be cool too but not necessary...
