Very informative content! Thank you. I want to add something though. Today, I went to a local Apple store to physically see the 13" air against 11" ipad, both with 256GB memory. There is no way I would pay for $500+ for the 11" regular ipad. The ipad air has so much more to offer for another $400: a stronger, laminated screen, preventing sun glare and thus rendering better images, a better platform if you actually want to draw something, and the possibility to use it as a laptop. The thing that stopped me was the Apple keyboard that cannot be detached from the screen support. BUT, Logitech also makes one for the 13" air that you can detach. So, if you want to use it as a screen to enjoy a movie without the keyboard in sight you can with Logitech. If you want to use it as a laptop, you simply place the air inside the Logitech cover.
