I will note by saying I have a fully functional iPad 2 (ios8 unfortunately) that I love. Use it for movies when traveling and day to day stuff. But I know I need to upgrade soon since there is a crack in the screen that seems to be ever-so-slightly growing. Now I am a huge analyzer of what I need and what I want. So iPad 2 currently hits all my needs. But I know I need to upgrade soon. My question is... what do I need to upgrade to. Is the Ipad Air 2 worth the cost of say... and iPad Air Refurb? Does anyone see more uses with the mini vs the full size? I have a bookbag for travel so size doesnt really seem to be an issue. And i would rarely just grab a mini and walk down the street with it (Boston). Any iPad 2 to Air/Air 2 advice would be welcomed. Just not sure I want to bite the bullet or wait til iPad 2 dies.
