Main reasons for me willing to switch to 12.9 from 10.5:
-much bigger screen
-moar! RAM
Thats it. If they released, say, iPad Air 4+ or whatever theyd call it, with around the same screen size as 12.9 Pro, Id get that one instead. I believe that current Air 4 is rather good iPad given that Pro 11 ir considerably more expensive. Base storage on new Air is stuck at 64Gb though, which, IMHO, today is less than adequate and 128Gb should be the norm on Air and at least 64Gb on regular iPad, and 256Gb on Pro.
I can see the difference between 60Hz and 120Hz when browsing/swiping, however I usually turn off all the bells and whistles to save some extra juice, so, 120Hz is not a must for me, not playing games on it either.
