Hi,
It depends what you want. If you just want it for music, you can get the iPod shuffle, it has one butten and works with voiceover.
I'm not sure about all the features of the iPod nano, I know it has more space than the shuffle, has a tutchscreen and works with voiceover.
But if you want apps installed, as well as to listen to music or videos, the iPod tutch is the best. You can also browse the internet. Voiceover just needs to be activated.
