I'm with SuperDave on this.
I don't like the Windows 8 Metro Interface. It's designed for a touch screen.
It is designed for a touch screen but it works very well with a mouse also. Using a mouse wheel makes scrolling the Start screen quick and easy. Or, the scroll bar at the bottom of the screen can be used.
You always have to switch to the Windows Desktop to do anything
And, switching to the Desktop is a matter of one click on the Desktop tile.
There are no menus on the apps, i.e. File, Edit, View...
Generally, the apps are designed for one specific purpose, so there's no need for the common File, Edit, View... menu approach. And, right clicking on an app will usually display some options for the user to modify how they want to use the app. For example, with the Weather app (one of the pre-installed apps which I believe is a standard app on all new Windows 8 installations), right clicking displays controls at the bottom of the screen to change location for the weather's reporting of data and to change from Fahrenheit to Celsius.
