An interesting book with some fabulous chapters (and a couple that bored me) but overall it kind of missed the point - or maybe that IS the point.
Gladwell's premise for this book is that we can all learn to use split second impressions to make important decisions - but he then goes on to demonstrate that actually, the opinion we form in the "blink" of an eye might not be the right one. Take the Pepsi taste test, for example - if you take a sip, Pepsi wins over Coke every time - but testing over a whole can or a crate shows Coke to be the preferred drink.
The overall message here seems to be that if you are very experienced or knowledgeable in a certain area then you CAN rely on first impressions but the rest of us should actually go for the long haul!
That said, I did thoroughly enjoy this book, especially the chapter on Kenna - and having listened to some snippets of his work I've ordered one of his albums too!
