Which is better iPod nano 7th gen or iPod touch 4th gen
I currently have an iPod touch 2nd gen 8 GB. I can no longer update it nor download from iTunes. I also do not have enough memory for all my videos and music. So I am considering buying a new one. I basically only use my iPod for music and videos and carry it in my backpack when riding the bus. I am trying to decide between the newest iPod nano and the 4 th gen touch. I am a little leery of the nano's small screen, but I've heard the 4th gen touches have extremely fragile screens. I don't care about retina screens or ability to watch HD videos, as I am visually impaired and can't tell the difference. What is most important to me is which one is more durable. Which one is less likely to be damaged considering I use it traveling on public transportation?
