Hey fellas, I'm considering buying a Nano or a iPod touch. It would be my first apple music player. Do these players only play m4a files? I need it to also play mp3 files. I also would prefer it to have Bluetooth. Thanks in advance.
They can play mp3's. You simply add them to your itunes library like you do anything else that you want to get on the device.
they both have bluetooth, if you have a Galaxy S2 already, I'd suggest getting the Nano. Having a smartphone already kills the advantages of getting an iPod touch. Don't think its worth spending twice the amount for the same 16GB if your just going to use it as an MP3 player. I know the the 4th gen iPod Touch is $199 but if you think your S2 is already bulky, then go ahead and get the Nano.
Buy a use first gen nano for 40 bucks and you can get a replacement current gen nano for free from Apple.
