Snickersnack: Odd, I find grabbing the top of the screen and dragging it to the bottom is easier than hitting a close button. Unlike the close button, you can't miss. You can literally do it with your eyes closed.
That's a valid matter of preference. Thus the smart way to design it would have been to have both the classical option available, as well as the new option (thus allowing people to choose for themselves what they find easier).
kavazovangel: That is valid for desktop applications, which you can close by pressing the red X button. :p Metro applications, when not used , are smartly managed by the OS and barely use any system resources.
I find it very rare that a computer program is able to manage things more smartly than I am (and even if it does manage to do so the majority of the time, there still needs to be the option to easily tell it to fuck right off in the cases where in trying to "smartly" manage things it's just making itself a royal pain in the ass). If I want a program to remain open, I will leave it open. If I want to close it, I should be able to close it without any hassles.
And you still haven't answered my question.
