Microsoft leads the way
From the viewpoint of a designer, it was clear that PCs needed a fresh face. Although Microsoft has always been the undisputed technical leader in operating systems, the windows and icons metaphor has become rather tired. Worse, file icons and shortcuts mar what could otherwise be a pristine desktop, and the ability to simultaneously view multiple applications forces the user to multitask, distracting from the most important task at hand.
But change is afoot, and Metro+Windows 8 is designed to play a pivotal role in Microsoft's bold leadership into a future awash with touch-centric devices. Metro isn't just pretty: It's efficient and supports quick navigation. Unfortunately, because it represents a bold new user interface paradigm, Microsoft needs to reeducate citizens and gently help them to become part of this brighter, shinier future of computing. That's why these Microsoft "retail stores" are so necessary, even if as a cost center they end up taking a loss.
