My in-laws are doing the same. Took MIL to costco to get her new tablet, and set up all the JW garbage on it. Now teaching her how to use it. For now, we are practicing "reply to an email." Next I will teach her "write a new email."
She replied to an email last night something like this:
How do I get apps? YOU CAN SEE TAHT I HAVE GOTTEN STUCK WITH CAPITAL LETTERS AND I DON'T KNOW HOW TO TURN IT OFF. MAYBE YOU CAN HELP ME WITH THIS BUT i WILL SIGN OFF FOR NOW.
omg I laughed 'til I cried. I have to admit, I'm getting my money's worth for the entertainment value. The inlaws are in their 70s and 80s, and can barely operate a basic flip cellphone. They haven't asked for a ROKU yet...
