My parents are both 50+. My Dad's a Sales guy and my mom is a high school teacher in a primarily non-English, government school. They use Ubuntu for all their tasks. Mostly includes Browsing(YouTube, Epapers), talking to my sister in the States (Hangouts), Media (music, photos and videos) and LibreOffice. The stuff they discover sometimes amazes me, all along I've been believing this would be too hard for them.
