-no easy access to all your files with file explorer
-mp3 cannot just copy in and out
-cannot send mp3 to friend, photos have to use special apps (bluetooth is like there for decoration)
-cannot use device like usb thumb drive
-put in custom ringtones need a lot of steps and need to do it in itunes
