my mp3 player is broken , so I want to change it for an mp4 player . Can you offer any advice about which brand and model to buy ?   an mp4 player ? why don't you buy a new cell phone ? You can find an mp4 player inside any of the latest cell phones .   Oh , that's a good idea . Perhaps I should have a try .   look at my cell phone . I can listen to music , watch movies , take pictures , play games , surf the web and download documents . It's just like a PAD .   that's cool . I can use the computer and the internet pretty well , but I'm a little bit slow in the latest trends of digital products .   that's Ok . you know , digital devices are becoming smaller and easier to carry , and they won't cost you too much .   yeah , if I buy a cell phone like this , I don't have to take a music player everywhere I go , and I can save the cost of buying an extra mp4 .   that's right . what's the flash memory of your old mp3 ?   256MB .   then any cell phone can meet your need because they generally have memories of over 512MB .
