Did you have a reason to expect the Verizon music software to work on your MBP? It's not like you can plug a Zune into your MBP either....
It sounds to me like you acted impetuously and you want someone else to take the blame for it. Sorry.
I'm not sure how reading reviews was really acting impetuously. There was an entire article where they compared the LG Voyager to the iPhone and gave point by point comments and the LG Voyager won out.
A few months ago I did ask to see an iPhone at an AT&T. I fully admit that I probably should have tried out a Voyager.
I would have accepted paying a restocking fee or some such, but fortunately it didn't come to that.
