Why is that? I'm probably gonna buy the Air just for taking notes / drawing unless the 120hz is really that much of a difference in the pro (have to compare it in real life). But I would never edit pictures or cutting videos on it so I don't really know why people need so much power in a tablet. Sure not for gaming, because gamers would be on windows systems anyway. 64gb is also plenty enough, storage is in the cloud. If I would need the 128gb version then I would also tend to buy the pro but with 64gb price is allright.
I am using iPad Pro myself but am going to get Air for my sister. If you are going to use it for notes though and planning to use the pencil a lot, then get Pro instead as pencil latency improves massively on Pro (I’ve compared it to original iPad Pro 10.5 and iPad 7th gen.)
