I've read two of his books - Blink and Outliers.
I agreed with some of the chapters but not all, especially with that of the Maths abilities in Asians. Being an Asian myself, I found it a little incredible at times, I mean, Singapore was never a rice-growing nation to start with... we are not even agricultural... our roots are actually in trade (which may mean that we understood the value of numbers from our forefathers). On the concepts of the miscommunication and positive effects of 10,000 hours of practice to confer benefits to one, I fully agree with him.
My main takeaway from reading his book: as parents, we have to persevere with our practices - so that our kids are primmed to make use of opportunities that appear in their lives. What we might not be able to, though, is that we may not recognise an opportunity when it presents itself. Anyone here has an idea on this?
