Microsoft Mobile Development Handbook now on Amazon
My colleague in the UK Daniel Moth has just had his book published covering everything there is about development for mobile and embedded devices using .NET Compact Framework v2.0 and VS2005 (and also bits on v3.5 and VS2008, referred to as “Orcas” in the book).
And some further background is here:

It's definitely a great read for developers looking to get up to speed with the latest (and greatest) tools from Microsoft.
