I want to know the answer to the following question:
What were the perceived problems with the new Windows 8 user interface?
All the background I'm provided with is that "Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system was widely criticized for being potentially confusing and difficult to learn (especially when used with a keyboard and mouse instead of a touchscreen).". Is that enough to answer the question?
Answer: yes
