This is likely to be the death of most "mp3" players.
Indeed. That happened to Walkman, Diskman, and so on. I think it is cheaper to buy a cellphone that allows you to hear radio, your music, to navigate, and most of the activities that were "apart". Until they merge cellphones and computers... cellphones with music are the way to go.

Needless to say that cellphones of this era can play videos. Like an "mp4" can do. Even new televisors can reproduct music stored in cellphones!
