I've just finished this book. Well, my impression is mixed. This is a solid product from the reputable resource, however, I didn't find much for myself in it. It was a worthwhile reading though.
It's sold exclusively by the Smashing Magazine, and I had a chance to get it with 20% discount and free shipping my pre-ordering. It's a little bit on expensive side now ($29.90 plus shipping costs), but the print is great. (However, because of the format, I wasn't feeling comfortable reading it -- to tight and small.)
If you're in the Web business, and, especially, designing stuff, make sure to take a look at it.
