I plan on purchasing the iPhone 5, and I'm trying to decide on capacity. I currently have a 16GB iPhone 4, and it's served me well. I've never really had to delete anything to free up space, but I don't keep a ton of music on it. I have a 16GB iPod nano. However, I have about 20GB of music, so I have to pick and choose which songs get put onto my iPod...for me, that's like asking me to pick between my children - haha. My question is whether I should buy an iPhone and larger iPod, or if I should just use that money to purchase a larger capacity iPhone. Would all that music slow my phone down?
