We love it, have it in both our cars. Since we got it a few years back we don't spend $$ on iTunes anymore for music. Use Pandora for mobile and Sirius/XM in the cars. Living in CO it's nice in the mountains where there's poor/intermittent or no cell signal and also no standard radio signal.

I don't do the streaming at home, I think it's dumb that this costs extra since I already pay for two car subscriptions.

Sounds quality is better than regular radio but nowhere near MP3 or CD. My experience (having had Sirius/XM on 5 different cars) the sound quality is highly dependent on how the car radio is configured by the automaker. For example my Ford and Subaru's had no special settings for Sirius/XM and the sound quality was poor. My Silverado and S60 (current cars) have a bunch of special features (surround, equalizer, etc) under the Sirius/XM input that really helps the sound quality. The Silverado has a DVR type feature that lets you tag and record songs you like, also rewind, pause (for hours on end) and fast forward (only if you have rewound already), very cool.
