My current iPad is 32GB. Works for me as I don't keep much stored locally. When downloading udemy course, I only download enough for my commutes maybe a little bit longer then it should be accounting for delays. So 32 GB works for me. I am going to upgrade my iPad soon though, but for the screen size not storage. Current iPad is a 9.7 iPad Pro and I am going to move to the 12.9" Pro. So for me, now that the minimum storage is 64GB that is perfect for me.
