Since OP seems to be keeping an eye on this thread, I'll ask here: have you considered using other tablets (Samsung etc.)? In case you did, and it didn't work as well as the iPad: what makes the iPad the ideal device in kindergarten? Construction quality? Software/Apps?
This is Apple’s marketing so obviously it’s biased, but here: https://www.apple.com/education/products/ How good is augmented reality on generic tablets? ..just as one example. Many people criticizing iPads haven’t used them for education recently or haven’t been trained on how to fully leverage the tech effectively. The curriculum assistance, available (quality) apps and overall device versatily are unmatched by com…
There is nothing on that marketing page that seems to especially improve learning vs. physical materials for anyone under about 10 years old. And frankly most stuff for 10–15 year olds can still (a) probably be done as well if not better using physical materials, and (b) isn’t significantly different between an iPad and a laptop or desktop machine, and often could be done on a machine shared by several students working together or taking turns.
I can well imagine that someone trying to learn how to program might want to use some kind of computer, but even then why an iPad instead of a little turtle robot that responds to Logo, or whatever?
Someone trying to learn how to make electronic music or edit video might get a lot of mileage out of computers (iPad or otherwise) but I can’t imagine this has become a core part of the school pedagogy.
I can also imagine that for anyone in middle school and up there might be a big benefit to carrying an iPad around instead of a giant backpack stuffed with 5 separate overweight textbooks. Though there are some advantages to the physical books too.

Instead of telling a bunch of skeptical non-teacher techies that we “haven’t been trained on how to fully leverage the tech”, maybe you can explain what that training would entail?
What in your experience has the iPad been so powerful for that couldn’t be done without computers? What age kids are you working with, and what are they working on?
