Re: SO,
It took me less than a day to get used to the Min/max/close being on the left of the title bar, and I've been using PCs since the days of the venerable Intel 8088. Moreover I use Windows too, and there is no confusion mixing and matching my daily use between Unity and various Windows desktops. Your brain gets used to it very quickly and it's nothing to worry about. Really. There are plenty of things to worry about with computers, and window control positions are not one of them.
Learning to touch type in Cyrillic when you're not from the region and you're not a young nipper -- now that's hard.
