And of the 4 models they offer they're all limited to 64gb of storage with the exception of the 6th gen iPad you can choose from 64gb or 128gb. I already own a 64gb LTE 10.5 iPad Pro but would love more storage. I hear down the road they will let you bring over your own iPads so I'm waiting patiently for that or holding off buying another until they offer better choices.
I don't know but I do know for a fact that the only NEW models are the iPad Air 3 (the one I got last week) and the iPad Mini. The iPad Pro they have is the 10.5 version and the iPad is not a new one. Not saying there is anything wrong with them, but when I was at the store I thought the website might be wrong so I asked about the Pro first but was told that they do not offer the brand new Pro.
