On desktop I do dualboot kubuntu (encrypted root and home) and windows. On servers I use opensuse or ubuntu. Kubuntu is my primary dekstop os for about 7 years now at work and at home. Windows I use only for games. I'm using ubuntu not because I like it, but because most things work with it. I've been using also opensuse on desktop for a year or so, but I like when things work. Using printer, scanner, or whatever, is usually impossible on other distro than ubuntu. On windows everything works out of the box, but I don't want to pay comfort with my privacy. On ubuntu it costs some effort, but with other distros it costs me so much time with everything I can think of. That time I want to spend better than figuring out why this or that does not work.
