Yeah. Sometime last year, my iPad Air 2 was beginning to feel a bit slow and I planned to upgrade to the first iPad Pro which supports 3d Touch. Since then though iOS updates have sped it up and it's back to kicking arse.Besides a faster processor and Apple Pencil support for the 2018 model, nothing really. I prefer the Air 2 due to its laminated display. It feels so much better than the 2017 iPad which has a noticeable springy feel when tapping the screen.
Right now I'm feeling I can keep it going for quite a while longer.
