What I hate is that the locales assume that date & number preferences are specific to one's physical location. I live in America, but I prefer German (9. March 2016 or 09.03.16) or British (9 March 2016 or 9/3/16) dates. It's even worse when things assume that my date preferences reflect my unit preferences. I prefer standard units (feet, pounds, knots &c.) and British/Continental dates: I don't want to use French units, nor do I want to use American dates. And yet so much software assumes that it's all or nothing.
