There is no upside to the iPad Air unless you have poor vision. $100 cheaper, same specs, more portable, lighter, higher DPI screen.
This is simply nonsense. Forget screen resolution, cost, weight, speed, memory, color...forget everything else. The mini is simply too small for some people...me included?
I would love to love the mini. My wife has a mini and I have used it extensively, but it is just too small for my tastes. It could be $300 less than a full sized iPad and I would not buy it. That's just me! It does not make it a poor decision for others!
Why on earth is this a recurring debate? It is completely a matter of preference!
