Well the problem with that is data caps. If you have a bunch of music you listen to on your phone, it makes no sense to stream it, using all your data for something that could be local. 16 Gigs is a fair amount, but if you don't want to have to pick and choose what music from your library you want and have to keep interchanging it all the time, then 16Gb is not a whole lot to be honest. If Verizon brings back the unlimited data option however, then hell, I probably wouldn't need more than 4 gigs either! Alas, that is not the case, and those of us who have lost the unlimited plan would rather not waste the data on things that shouldn't have to eat into the data cap
