I set my mom (62) up an old laptop running Ubuntu last year when her laptop was stolen out of my sister’s car. She’s adjusted fairly well to it. She needed a lot of hands on support at first and any time she uses her printer, but she has figured out how to do a lot of things on it on her own.
She makes papercraft activities in inkscape for a weekly storytime she hosts at a bookstore and has gotten very proficient, but still needs some hand holding when printing errors crop up.
New Zealand I’ve never been and know little about the day to day life of a new zealander, but it looks so beautiful and quiet there.
