I just picked up a Nano 6th generation yesterday as my first apple product. Today, I'm thinking about picking up an Ipad. If all I do is surf the net would you say an Ipad 1 16gb is good enough? I know the Ipad 2 is faster but I wouldn't think it would make that much of a difference for web browsing? If so, should I buy refurb or new? Thanks in advance!
