I want to know the answer to the following question:
Who said the Windows 8 interface was clumsy and impractical?
All the background I'm provided with is that "Despite this "stumbling block", Bright said that Windows 8's interface worked well in some places, but began to feel incoherent when switching between the "Metro" and desktop environments, sometimes through inconsistent means.". Is that enough to answer the question?
Answer: no
