The new interface in Windows Vista. Aero uses hardware rendering, and thus is smoother than previous
Windows interfaces. It allows application
windows to have translucent borders, and allows you to flip through your
windows in 3D.
Aero was originally an acronym for "Authentic, Energetic, Reflective, Open". However this acronym has been dropped.
Aero requires a premium edition of Vista (Home Premium, Business, Ultimate), at least 1GB of RAM, and a 128MB 3D-enabled video card.
