Thought I would beat the Christmas rush and purchased two 16G iPad mini's with Retina display for both my wife and college age daughter for Christmas but now I'm seconding guessing myself on if they might be to small at only 16G. For the most part they will be using them 90% for surfing the internet and watching a movie here and there on a plane. Photos would be the only other big use I'm guessing. Having spent almost $1,000 including smart covers, I hate the thought of having to return them for a 32G model at $200. more. Any thoughts or advise?
