Hi, I have an iPhone 5 (32gb). I have around 30gb of music so I need to reduce down to 128, to fit all my music on it. I listen all day to my music while at work, using a speaker by Bluetooth. It runs my battery down, before the end of the day, so I was thinking of a iPod touch 64gb and carry both during the day. I don't need the iPod touch for anything other than my music, so am I foolish to buy touch? The Nano is only 16gb and need more space for my music. Thanks
