I had The chance to play a few minutes with an iPad Air yesterday. It wasn't installed yet, just showing the Hello screen, so I didn't have any experience with its speed, but well it runs iOS7 and it's probably faster than my iPad mini, so it's not really that necessary to review the device.
What interested me more was how the device felt. And compared, yet again, to my mini, it's oh so light. Apple really managed to take the lightness of the mini and scale it up to a full size iPad. The Air truly feels and handles as an iPad mini with a bigger screen. It balanced the same way and somehow they feel equally heavy.
Am I gonna buy it? Probably not. I like how it feels and handles but I like the smallness of the mini more.
But it's one sexy iPad. That's for sure.
