"The Charms may be curiously named, but they provide a very important interface between the otherwise separate Metro and desktop experiences in Windows 8. Available from any interface—the Start screen, PC Settings, any Metro-style app, and even the desktop—the Charms consolidate many important system-level capabilities and often-needed features into an easily remembered and accessed user interface that otherwise isn’t taking up any valuable onscreen real estate. As such, it’s a great Metro user interface, and the embodiment of what this design style is trying to achieve." - LANjackal from Bookmarklet
