I've been thinking about it, the 1TB version that also comes with 6GB Ram is probably more future proof, i don't particularly like using that word but in this case it may be true. With Apple's arcade game service coming out later this year, full Photoshop and LumaFusion 2.0 on the way, these are all likely going to take advantage of the 6GB Ram.
My mother needs a new upgrade from my Air 2 which i gave her back in 2015 when i brought the first iPad Pro, i'm very tempted to give her my 2017 iPad Pro and buy this new one. At least it will last for a while, especially since Apple updated the design and gave it Face ID, so i don't see them adding anything to drastic this year or even next year.
