The larger screen was, for me, the biggest concern in switching back from the iPad mini to the iPad Air. After an initial period of shock where every iPad app looked unreasonably large and spacious, three months of daily usage have rewired my perception of the Air's screen size. I prefer the Air's bigger screen to the mini one now, but only because the design changes in the latest model make it as comfortable and painless as the mini to hold with one or two hands. The iPad is, after all, a screen that you keep in your hands, and the practical consequences of that screen are a product of the comfort you find in holding the device.
I could quote damn near his entire post. The iPad I near perfect, it just needs to be a touch bigger.
