My wife works at "In-Home healthcare" for the elderly community, specializing in hospice care. Because of this, she sees a lot of family members who get their parents tablets. It can be an iPad, or Android tablet. And it's used to facilitate cheap/free communication. (Don't worry, anything with app stores + in app payments are at fault, not $your_ecosystem.)
The dark side, is when they start venturing around looking for "games". Now, think of what a game was 20 and 30 years ago. We're talking arcade, Nintendo, Atari.. That sort of thing. The psychological skinner-box wasn't really created as of yet (it was, but only in arcades, and even the bad ones people stayed away from).
And then you have the "Freemium Apps". AKA money-bilking skinner boxes. Now, what makes these insidious, is the fact they ask for your credit card once, and keep it on file. Now, buying "virtual trash" is as easy as click click done. And conveniently drains your card.
And it's done so well that you think you're doing with fake play money - when it's really your real account.
My wife's already had a few clients got bit by this. It was a few thousand dollars, but enough to cause serious problems with someone who is on a fixed budget. Fortunately, the bank reversed much of it as fraudulent billing. Some of it was outside of dispute period, and was lost.
