Best books/ info sources on UI design

Not sure how advanced you are, but as a relative noob, I've been reading, among others, the following sites:

http://www.smashingmagazine.com/ http://uxmagazine.com/

Smashing has really good books, most if not all you can buy as ebooks. If you want a good overall primer for less advanced UI/UX designers, read the Smashing Book #1

I've read a few books about the subject. One of my favorites is Designing The Obvious by Robert Hoekman Jr: http://www.amazon.com/Designing-Obvious-Common-Approach-Appl...

What about http://www.designforhackers.com/ ? I havent read it (im not an UI guy)

Highly recommended.
