Well, an iPad can do a lot more than YouTube and Instagram. For someone with as simple needs as your family member...an iPad can easily replace a laptop. If you have an iPad...show them what it can do, especially in regards to their needs. And yes,
there are many keyboard cases for the iPad. Personally, I would go for the
Logitech Combo Touch.
I have had one on my M1 iPad Pro 11 for over 3 years now, and it works like the day I got it. It has also protected my iPad through 3 falls. Just my 2 cents.😊
You are also welcome to show your family member the two links in my signature related to the iPad.😉
Don't know why the Amazon disclaimer is there. I don't work for or represent Amazon. Must be the links in my post.
