There are many ways that Expression Blend can be described—who it is aimed at and
how it should be used.
My view will be different from the next guy or gal, and the one after that. All I know is
that I have used this tool almost on a daily basis for several years now on every platform
that it supports, and it just keeps getting better and better.
User experience and interactive design is an ever more important part of the solution
creation life cycle and the richer the platforms become that Expression Blend supports,
the greater the need for this tool, which can assist that process to be imparted into the
production solution, working from initial sketches, wireframes, and prototypes, and then
through to production implementation.
Expression Blend 4 represents a real step forward in providing designers and developers
with the ability to collaborate, as well as to help developers who need a more robust
design tool (other than Visual Studio) when working with user interfaces. Blend has
matured to the point that very little, if any, code or XAML scripting knowledge is
required for the majority of tasks that it allows you to perform, and this book aims to
show you how to work in that manner in clear and as much as possible non-technical
language.
