I agree with this. My grandmother (who passed away in 2018 at the age of 91) tried to get into computers regularly for a decade, starting in the early 2000. We tried a lot of things, nothing stuck. Every device we would give her would quickly gather dust, unused after a few days.
Then in 2013 she got an iPad 2 and she instantly started using it several hours a day for the next five years.
In particular, I set it up so I could push new family photographs to her iPad remotely through iCloud. That was absolutely life-changing for her: now she was able to see super recent photos of all her children and grandchildren without having to beg for a printed version. That also worked for videos: for the first time since the VHS days she could replay family videos whenever she wanted.
She also liked multiple card games and the iPad was a wonderful device to play them electronically. The biggest self-service I ever gave myself was to only suggest games that had a paying version without ads, and pay a few euros to buy them. The biggest problems with ads for her was that she could sometimes be a bit sloppy with the touchscreen : when an ad was present it would redirect her to a random website and she would get lost. The quality of the iPad touchscreen and that we stuck to ad-free apps allowed her to almost never get lost like this anymore.
While the iPad may not have been a revolution for the general population, it definitely changed the world for my grandmother. For that I will be grateful for this device to exist.
Miss you, grandma.
