Bottom line: Birnbaum's maybe all 'pretty' & colorful, but this book has what you really need to know, & the fact that it's 'unofficial' just signifies that it's unbiased & written by those who experience WDW just like the rest of us, the good and the bad. And it certainly doesn't hurt that they somehow manage to make every section intelligently written, easy to understand, & humorous all at the same time. It makes for a great read even if all you can do for now is dream of going.
