How much mobile music do you need?
I often go away for 3 - 4 weeks away from my beloved library, my 128 ipad gives me say 300 flac Albums.
With a Audioquest Dragonfly Red, and my traveling phones , Bose QC 25 , I am perfectly happy
South African data costs make a mobile option far too expensive. My 3gig package runs out at $25
