I have Air 2 and IPP 12.9 since the release date. I really enjoy using the IPP more than the Air 2. I only use the Air 2 when I am out and about. My daughter who is graphic art school asked if she can have my IPP 12.9, and I gave it to her. During Christmas sale, I couldn't resist picking up IPP 9.7 128GB for $550. So, I bought it. After using it for few days, I asked my daughter to pick the 9.7 or 12.9? she decided to go with IPP 9.7 and I took back my IPP 12.9. All in all, I seem to enjoy using the IPP 12.9 more than the 9.7. To be honest, yes IPP 9.7 has few additional features compare to Air 2; but I don't see much of a real differences between the two for what/how I used it.
