Also very annoying to be thrown out of your app when you just want to run a calculator or something small. Even more annoying when that calculator has to run full screen (or you have to waste time snapping it to some side).

I haven't actually used Windows 8 because I've heard it's so terrible. What I don't understand is this:

> In the future, all of Microsoft’s Universal Windows apps will also run in a window.

What does this mean? Are you telling me that every program I run in Windows 8 is full screen? That's the dumbest thing I've ever heard. The OS is called WINDOWS.

Every Metro app is full-screen, every normal Windows app runs in the desktop. It's remarkably annoying to have both paradigms forced on you.

When I want a calculator, I type:

Windows Key -> "calc" -> Enter

Viola, the classic Windows calculator.

Even easier: use the url bar as a calculator. Google has handled math as a seach for a while now, and it's pretty good [1]. No need to leave the browser.

Sure, but one is not always in the browser ;)

True, while metro is really quite nice on a tablet, it is downright terrible with a mouse. I think this could be relieved by scaling down all the tiles on a mouse-and-keyboard setup.

But to me, thats an entirely different concern. It's frustrating that most users, of any platform, will simply scream and give up whenever there's a change in their routine.
