While I'm a huge Gladwell critic, I enjoyed that book quite a bit. But I disagree with your main point. I'd summarize it's conclusions as:
1. People make decisions very quickly -- like often in under a second.
2. These decisions are very powerful.
2a. Powerful in terms of accurately deducing things, and/or
2b. Powerfully emotional in how it sways you (not always in good ways!)
3. You can have some success in retraining your fast decision making.
This may seem slight, but I think these three main points are not necessarily obvious and are probably true. I've taken advantage of these by, for example, researching different mobile phones a bunch but consciously not making a decision until I walked into the store and I had a powerful interest in one of them on the shelf. That turned out to be the right answer for me.
