iOS 11 feature-wise, does the 1st gen 12.9 have everything the 2nd gen 10.5 and 12.9 do?
I would think so... only difference are the internals. That’s why I’m not in no rush.
The 1st gen 12.9” iPP has 4gigs with all the new multitasking iOS 11 provides, I did the split screen apps and a floating app along with PiP.
