Re: Are smart phones making MP3 players obsolete?
yes, mp3 players are going the way of the dinos (scary to think that I owned a mp3 player before the ipod was ever released and now I'm writing about the standalone mp3 player going away)
However, I don't think it will be b/c of your phone per say, but b/c of the cloud. Eventually your stereo will be connected thru the internet to a list of songs you've selected on the web. You're phone will be connected to the same list of songs, as well as your car, TV, etc... There will probably be something of similar size to the nano, but rather than storing songs, it will have a wireless connection to the cloud for people that like to take their music out on a run, but don't want to risk dropping their phone while out on that run or while in the gym, etc...
In the future, I think many of us will still have a home computer that will act as a sever storing movies, songs and what not off of the cloud to avoid the wireless costs, but that computer will connect to most of the things w/n the house to transmit that data for our enjoyment.
