Best Business Books of 2011 (IMHO)

I read more than most people, on average 2-3 business books per month. That adds up to a lot of books over the years.
I am very picky. Before deciding to read a book, I do a ton of research, review reading and other due diligence. I don’t read cheesy business motivational books. My last years favorite was Rework (if you haven’t read it yet, do it).
