In response to his specific points - this. In response to his response as a response to my response, I'd add that if he wants to see progress on these issues, Linux isn't ever going to burst into the room, take him by the hand and whisk him away. At some point he's going to need to take the leap and start using Linux in anger in order to escape W7 or W10. His wife running Ubuntu is encouraging though. I'm much happier if someone has at least tried Linux rather than just assuming it's terrible. But as I say, everyone needs to take a step forward of we want to move the front line.
