Bought the latest 12.9 IPP back in December, 2018. Was at home doing dialysis. Turned to pick up my phone and the IPP (in a protective cover case, opened and flipped back for use) caught the edge of my elbow. It made one full axis rotation and landed flat down on a hardwood floor. height about 3 1/2 feet. Caused a thin hairline crack running diagonally. You have to rotate it ‘just so’ in direct light to see the crack or you can feel it by running the pencil across the screen.
Didn’t have AppleCare since I rarely leave my house. Apple quoted me $849 to replace the screen. Everything still works 100% and since I don’t intend on selling it, I used that $ and bought a 9.7” iPad/pencil as a backup just in case.
I’ll buy the new 12.9 IPP whenever it comes out and give the damaged one to my sister, even though she doesn’t use the Surface Go/pencil I gave her a year ago.
If my IPP had been rendered non useable, well that would have been a pickle (repair or buy a new one to replace).
