Personally, I regularly charge my phone and listen to music through the 3.5mm jack at the same time when I'm driving (my car doesn't have Bluetooth, so I have to use one of those 3.5mm-to-cassette adapters). Using a phone that doesn't have a 3.5mm jack would mean needing to burn quite a bit more money to somehow wire up my car for Bluetooth if I want to still be able to do these things.
