“A reasonable user might respond to this dog’s breakfast of a user interface by trying to stick with either the familiar desktop or the new tablet. However, this is not possible. Some functions, such as ‘start an application’ or ‘restart the computer’ are available only from the tablet interface. Conversely, when one is comfortably ensconced in a touch/tablet application, an additional click will fire up a Web browser, thereby causing the tablet to disappear in favor of the desktop. Many of the ‘apps’ that show up on the ‘all apps’ menu at the bottom of the screen (accessible only if you swipe down from the top of the screen) dump you right into the desktop on the first click.”
Windows 8 is quite possibly a bigger mess for Microsoft than was Vista. And Vista, at least, was relatively easy for the company to extricate itself from.
