My dad is currently using the iPad 3 (my very old iPad) and it's still working but frustratingly slow, he will be getting my 1st get 12.9" iPad Pro when i upgrade to either the 12.9" or the 10.5" iPad Pro, I haven't decided which one to get yet have you?
Yes, I have ordered the 10.5" 256GB WiFI model. I am not sure what to do with 256GB, but I figured 100€ more for 4 times the space might pay off at some point. Also, larger storage is usually faster. My iPad 3 is basically unusable at this point.
My secret hope is that for some work-related things I won't have to carry around my MacBook anymore, but will only bring the new iPad.
