I bought a mp3 no-brand shuttle. Had it for 3 years and suddenly it just stop playing and plus lost all of my music. I used it for ‘power walking’. Now, I really need the exercise an I am in need of a new player, I like the idea of the video and music opportunity, but is it really better just because it is newer! And the price is almost the same for both! The article on the differences in the players, didn’t help, I am not a computer expert, just use it because it’s a must for everything, now and the apps. and the educational value, is good too. Now please, what is the real difference, would you settle for a MP3 and not the MP4?
