I am very fond of the aero system theme that Microsoft introduced in Windows Vista and continued in Windows 7, so I am very displeased that Microsoft abandoned it in favor of the metro theme in Windows 8 and 10; aero looked so beautiful with its clear glass and shiny finish, while metro looks so flat and dull with its solid colors.
What does everyone else say about this? Why did Microsoft abandon aero for metro, and will aero ever return?
