I was disappointed by this book as it lacks any additional info or opinion that you can't easily find on the Azure Blogs, forums or slideshares. I am struggling to think of anything that I learned from the book that wasn't already well known and publicised. Perhaps if you have no previous insight into Windows Azure then you might gain more benefit that I did.
The book is 270+ pages long but thats because it has probably the biggest font-size and line-spacing I have ever seen in a book (it actually makes it hard to read). From that point of view making this a "volume 1 of 4" looks a bit overcooked.
I wouldn't rule out buying the next volume but I'll be a bit more cautious.
