Apple, for the convenience, simplicity and clean design. I've been a customer for almost 30 years, as well. Apple has been good to me.
Also, audiophilia doesn't matter much when I'm on the go or in the car. That the iPod isn't sonically perfect doesn't matter much. When I want to do serious, critical listening, there is the home rig. When I'm driving, in an airplane or out for a walk, I don't notice much the imperfect fidelity. When I'm at home, I'll light up the tubes, spin some vinyl and really dig into the music.
