You’re quite right. I tried to give my grandparents an iPad, but a few months ago I spent two or three hours trying to get them to reboot it and logged into FaceTime (over the phone). About half of that was literally trying to get them to reboot the iPad. They just couldn’t find and then hold down the power button. They were struggling to see it, and then struggled to hold down the button for long enough without releasing it. It was really really hard for them. I eventually gave up, and they were very frustrated with the iPad and themselves.
