Daniela Panfili from Smashing Design works in mobile experience design, and has taken a comprehensive look at the design elements of Windows Phone and Metro UI, and she likes what's on offer from Microsoft. Looking at the environment from a fresh perspective helps to remind us all just how revolutionary (and easy to use) Metro is.
The goal of the Metro UI is to emphasize important content in a way that helps the user determine whether to dive into it or keep doing what they’re doing. To make all of this possible, Microsoft has introduced the concept of the hub, whose role is to concentrate all of the information onto one screen, like a dashboard. A better analogy might be the cover of a digital magazine, such as Flipboard.
