It's funny that people are setting up Windows 8's Metro interface as diametrically opposed to the ribbon (or at least the ribbonization of Explorer) when isn't it the same person at the top responsible for both?

For that matter, the Metro “Start” UI (not sure what they call it) is more flexible with its layout than the Start menu (or a toolbar). Exposing the active content of applications follows Office 2007's Results-Oriented Design, like galleries are active previews of formatting options. The Office Ribbon solves a different problem – the proliferation of features in Office apps – but is a manifestation of the same spirit as Metro.

Is the Metro interface not a system ribbon?
