The Windows Phone Developer Team has recently tweeted about a short eBook on the Windows Phone 7 design system (codenamed Metro) and posted a link to download the PDF File.
The introduction:
“As we go through the process of building Windows Phone, we want to think about how we design and develop in ways that will set us apart.
This is a book that explains how we plan to do that through our design language, internally code named Metro, through our seven areas of differentiation, and through our Red Threads, or guiding principles.
To help tell the story, we introduce our muses, Anna, Miles and their son, Luca. They represent classic Life Maximizers busy personally and busy professionally, constantly juggling priorities, settled rather than seeking, and valuing technology as a means to an end, a way to get things done. Sound familiar?
Whether you’re new to Windows Phone, or you’ve been around for a while, we hope you’ll find in here the principles and values that will guide us moving forward.
Welcome to Windows Phone”

The eBook presents Metro’s seven areas of differentiation as well as the “Red Threads”, which are “the principles that guide the experiences we build”.
