Hello. I am considering to buy either the 32GB or 64GB iPod Touch. From the Apple website, it reads that the 32GB version can hold "Up to 7,000 songs", "Up to 40 hours video" while the 64GB version can hold twice as much. Does that mean the 32GB version can hold up to 7,000 songs AND 40 hours video? Since the new iPod Touch models do not have a camea, I cannot imagine most of us would need more than 32GB. Am I missing something? Can iPod Touch plays back PowerPoint or Keynote presentations? Usually how the storage are spent? I wonder if it is worth to pay extra to get the 64GB version. Thanks.
