Yesterday Microsoft released a video showing a preview of Windows 8. This is the first time that a preview of the user interface has been released to the public. It’s a WOW. It’s also scary. It’s the kind of leap that we made when we went from Windows 3.1 to Windows 95. Since 95 the Windows desktop has remained pretty much the same. Well, say goodbye to the well loved desktop and hello to the world of touch and tiles.
