I just got an iPad Mini a month or so ago and love it. My wife has an iPad 2 and after playing around with the Mini she was wondering if I'd want to trade. After playing with hers for a bit I felt that the non-Retina screen on both was more noticeable on the iPad 2. Is it just me or is this true because of the larger screen? Should I trade? There really isn't a spec difference is there?
