Wondering how many people went with the top storage option of 512GB? I'll be ordering the new 10.5" IPP next week. Leaning towards the max storage but might go with 256GB instead. I probably won't even use that much who knows what will happen while I have it over the next few years. I rather have to much storage over not enough. My current 64GB iPad Air 2 only has 2GB of storage left. I have that much because I deleted some apps until I get the new one.
