Where is Portable Music Heading?

Well, technology has come a long way in the past 32 years, it started out as a radio, and then advanced to cassette tapes, then the Cd was invented, then MP3 files, now you can just download anything you want, like movies, music, TV shows, you can download millions of apps, and record video all on you music player device. We wouldn't have had the Ipod invented if it wasn't for the MP3 players and all of the other ones that lead up to it. Technology has advanced so much, and who knows what it will look like in the future, maybe the devices will be the size of a dime, maybe you can customize the shape, just think of how many more apps will be invented, how much more music it will hold, and all the new music thats going to come out, it will be way more then just a music playing device. But you never know, maybe it will just stay the same for another 20 years, but I doubt that, if it has evolved so much in the past 30 years, why would it just stop now? We will just have to wait and see what happens, just imagine what will happen to the music playing market if it keeps advancing like it is? What will that look like next for portable music? I guess we will just have to wait and see.......
