Maybe you can help me win an argument...or come to my senses. I got caught up in the hype and am about to purchase an iPad Air 2 when my best friend asked me "What can the new iPad do that yours can't?" And I really didn't have a good answer. It can utilize Air Drop and Handoff, but other than what can it do that a 3 cannot? Then I started to doubt my own purchase. I mean thinner, lighter, faster...yes, but the basic idea of the iPad hasn't changed. How would you respond to this question?
