I want to know the answer to the following question:
What makes the Windows 8 interface difficult to use?
All the background I'm provided with is that "Bright wrote that its system of hot corners and edge swiping "wasn't very obvious" due to the lack of instructions provided by the operating system on the functions accessed through the user interface, even by the video tutorial added on the RTM release (which only instructed users to point at corners of the screen or swipe from its sides).". Is that enough to answer the question?
