I got all my grandparents iPads. The only tech support calls I get is when they forget their Apple ID passwords. Thankfully, I know them all.
till you're on vacation and they go to the apple store and they "helpfully" set a secure password on the device. Happened to my mom. She doesn't always remember to write things down. Now I'm on a 3 way call with apple trying to get the password reset for an hour then talking her through resetting it on her several devices. They wouldn't let her set what she thought the password was.
The iPad of my parents (that they use mostly at home) seems to insist on more complex security procedures for my parents to watch the pictures of the kids than the procedures which secured the launch US nuclear missiles (the later had simply the code 00000000 https://arstechnica.com/tech-policy/2013/12/launch-code-for-... ).
Balancing the security and usability is hard.
