I plan to get an ipad 3 in the next while and wonder how much memory I will need. I already have an iphone and plan to get a wi-fi only ipad. For the little time I will be away from wifi I feel that tethering to the iphone will work out OK. I don't download music or videos nor do I take videos. But I plan to have pictures for my business. Not thousands of pictures but perhaps a few hundred. I wonder if the 16 gb version will be adequate. Anyone have any suggestions? Thanks Fred Mc.
