how many of you own an iphone or other smartphone, and only use pandora on it for listening to music instead of your music collection? personally, i really hate having to use itunes to transfer music to my phone, but pandora streaming over 3g isn't always reliable and more of a battery drain. i might give it another try once 4.0 os comes out and i can run pandora in the background, but i'm always a little surprised when i hear that so many people use pandora exclusively for mobile music.
