Many of the patients are older folks. They tend to press long and hard on the big buttons.
A sensible app developer traps tap and long-touch, and sends them both to the same handler. This developer only catches the tap event, and ignores long-touch. The attendant was getting grumpy, because she had to keep telling patients "tap 'gently'."
It's just me, I know, but I get salty, when I see this kind of careless UI design (it was the app's fault -not the iPad's). I know that the medical group paid big bucks for the app.
Your district is liable to be unpleasantly surprised. Like ours, they will likely find middle school-ers are worse at caring for Chromebooks. The rate of broken Chromebooks for us was staggeringly high.
I think it tends to be the more well-off schools with the iPads, the chromebooks are definitely a lot cheaper over the long run for the district.
I'd need to seem some evidence for that - cheap chromebooks break very easily. Talk to any school IT person who handles device repair/replacement and you will hear nightmares of 50+% loss rates...
