@ayachan I might not like Windows, but that's never stopped me from using it at my day job. I figure that if people are using it at home, they probably have their reasons.
Use whatever works for you. I'd rather show off interesting ways to extend the life of old computers with UNIX than bully or cajole people who are content with Windows, because the hard sell never works.
UNIX isn't going away, and it'll still be around if you change your mind. In the meantime, do what's best for you.
