You don't owe me an apology dawg! I sold my G1 too, but I do love the Slacker service. The appeal for me is the customization of station and musically there just isn't anything out their that even comes close. I can't imagine not having it now!
I sold mine on Ebay after a week of ownership, not cause it was terrible, but I could see I was not going to use it because I already had a G2. Now my G2, you'd have to pry from my cold dead hands because that baby isn't going anywhere.
In regards to the service I don't think I've encountered anyone that has actually used it for any length of time that doesn't like it.
