This puts us in the exciting but challenging position of always being on the cutting edge.

10 Whenever platforms or tools are shipping out of Microsoft, which seems to be about every other week these days, we have to educate ourselves, quickly. Information is plentiful but harder to digest In reality, this translates into a lot of book orders, blog searches, and Twitter scans. While more information is becoming available on the Internet and more and more books are being published, even on topics that are relatively new, one aspect that continues to inhibit us is the inability to find concise technology overview books. We are usually faced with two options: read several 500+ page books or scour the web for relevant blog posts and other articles.
