What is the advantage of this mp4 compared to Ipod then?
Through the use of 2.5″ hard disk, we can allow much larger hard disk capacity compared to 1.8″ hard disk based mp3/mp4 players. In addition, our mp4 players are cheaper and have many useful functions such as build-in FM transmitter which is only possible on Ipod via 3rd party add-ons, causing users additional money and trouble to carry around.
