A friend asked me to fix their daughter’s desktop and also asked if she could borrow an old laptop to use in the meantime. The desktop was disgusting with food smeared all over the keys and display. I cleaned it up and fixed it and sent it back. My laptop was returned with food smeared everywhere after just a few days. I was stunned.
I never see this kind of stuff with XFCE. I run various flavors of Debian that do not go through Ubuntu.
