One does data I/O via read(2) and write(2) system calls. The IOCTL system call was a hack to allow you to send control messages to the driver. The whole purpose of the Unix symetrical I/O is to abstract devices into file I/O semantics. I belive you wantch movies and play music, etc. That does not make the interface semantically correct.
