"In my New York Times column on Thursday, I pointed out that Microsoft’s new Windows 8 feels like two operating systems in one. There’s the traditional desktop Windows, best for mouse and keyboard, and the new TileWorld (as I call it), best for touch screens.
"Why “best”? Because desktop Windows has tiny buttons, menus and controls that are generally too small for finger manipulation, and TileWorld is filled with gestures that make sense only on touch screens.
I"f you install Windows 8, you’ll have to learn both environments, like it or not; you can’t live in just one environment or the other. So the question arises: how are you supposed to operate TileWorld if you have a nontouch computer?
"Answer: There are mouse and keyboard equivalents for the touch gestures."
