Hey guys, I've been interested in buying a 7" tablet and everybody suggests the Nexus 7. Using giftcards lying around, I am able to buy 32GB version for $150+tax. I will mainly be using it to read PDFs, watch youtube videos and occasionally listen to audio. I feel the upgraded model won't make much of a difference to me. Is it worth it for me to wait for the newer model or just get this one?
