They Never Mention RAM Period. We always wait for a iFixit Tear Down to see the actual Chips
If they stick with 2GB RAM, I am gonna laugh so hard. My guess is 3GB to match the IPhone 7 Plus and IPhone 8 but who knows.
I think iOS 11 in the 9.7" Pro and well understood and fully Supported Resolution is the ultimate sweet spot.
The new 10.5" Awkward resolution some Apps will look off and there will be inevitable issues.
The 9.7" Pro might be the sweet spot for now, but it is no longer for sale, so 10.5" support will hopefully grow quickly. Although many developers may just use the standard 9.7".
There are now so many iOS options that resolution independence is the only way for developers to go.
