exactly, I have the A9X 12.9 and the maxed out A12X 11 pro with 6GB RAM, and I still use the first more because I like the larger screen, and it's fast enough. Now the iPad air 2 or the mini 4, they are painfully slow for me, but A9X and above I really don't mind, they are all fast enough that I almost don't care... it's like if the ipad air 2 were the atom/celeron computer, the A9X is the dual core i7 and the A12X is the quad core i7 (which is actually what they really are in terms of speed). Quad core i7 is faster sure, but dual core i7 is still so good that unless you do video editing most people don't really care... especially for iPad workflows
