Don't Make Me Think, Second Edition

A reader recently pointed out that the second edition of Don't Make Me Think is about to be released. I know I've pimped this book ad nauseam, but I can't help myself-- it's just that good. If you only read one book on usability and UI, it should be Krug's Don't Make Me Think. I even gave it to my wife to read, and she enjoyed it too. Is there any higher praise?

Unfortunately, Steve Krug's website doesn't have any information on what's new in this version. The yellow sidebar indicates "3 new chapters", but beyond that, who knows.

I'll be getting a copy of the new version for sure. I can keep the old one at home and the new one at work, or I can surprise an unsuspecting manager or fellow developer with the first edition. Now if only I could get them to read it..
