So I gave my ipad air away a while back in place for an iphone 6 plus and i want to get back in the ipad game. Now that the mini 4 is finally on par with the regular air, which should I get? My two concerns are: 1. Is the ipad mini 4 too small? 2. Do apps that run on the ipad mini run exactly the same as the iPad Air? Or do they have sizing issues?
