Just bought a P4 and my fingers are crossed it wasn't built on a Monday. I thought I had use of an iPad, but the family member has rescinded permission….so I guess I need to buy one. The apple store has iPad mini as refurbs for a decent price. These are wifi only and 16 Gig. Not the new Mini 4. For flying are these a good choice? I have pretty lousy vision and need all the help I can get, so flying it with my Android phone would not be good. My first post, hope to be a regular. Thanks in advance.
