I have had every version of the iPhone since it came out. And honestly, I never put music on it. Pandora has been my "go-to" app ever since its inception. I was using Pandora 7-8 years ago.
Today the iPhone finally got multi-tasking and made it so I can do everything I want and not have to end my Pandora session. Will there ever be a need for me to put music on now other than when I am on a plane and can't use the network?
I almost bought a droid just because of this one feature, now the iPhone has it. Thank you Apple for completely eliminating the need to buy music!
