I just noticed that Apple.com has refurbished 32gb 4th Gen for $179. Don't know if this is significant savings or their usual refurb price. My question is this: is it worth it for a $100+ upgrade to the 5th gen? I was looking for an upgrade in storage space from my current 8gb Touch . One advantage of buying the 4th gen is not having to concern myself with the lightning adapter. Any input would be appreciated. Thanks.
