As you can expect from Gladwell - lots of lots of interesting stats, lots of anecdotes and good story telling. But he does not go beyond the "safe" boundary and make bold statements or conclusions. Nevertheless, it is definitely a fun read and gives a good deal of new information and new perspectives.
The things that impresses me most about him is that he is interested in and collects information/anecdotes from people from all walks of life - from doctors to construction workers to dog trainers. Reading his articles, you realize how little you are exposed to, to people from fields that are not yours.
