Why don't people get it? They are ipods. Besides the ipod touch, they are bought to play music.
If I would use my phone to play music the battery would be dead by noon.
If it rains while im on a run, I only risk 120€ not 500-900€.
Not to mention that an ipod is WAY lighter (12.5-31g) compared to a smartphone (130g). Which makes it less iritating when you carry it in your pocket.
