I'm disappointed in there being no RAM update, but I guess the 12.9 display needs it more
. I still feel like the A9X will offer a big enough performance boost over the Air 2 when using CPU-intensive apps. Looking forward to the additional speakers, pencil support, and the 4K camera may prove to come in handy as a backup from time to time.
That said, I've had no real performance issues with my Air 2, and I agree that it's the better value right now (price wise). The 12.9 is also a better deal, but the size is too much for me. The iPad does not replace my MacBook or desktop, and there will still be lots of times where I'll need to be putting both an iPad and a MacBook in a backpack. Even at home in bed, where I use my iPad a lot, I don't want that big of a screen or the extra weight.
