Nielsen and Chuang 10th Anniversary Edition

Nielsen and Chuang's Quantum Computation and Quantum Information is considered to be a classic in the field. (I named it one of my top quantum computing books last year.) They're coming out with a 10th anniversary addition. You can preorder it here on Amazon, it is available at the end of January 2011. The new addition is hardcover and about what I paid for my paperback version. I recommend reading Nielsen's comments before you rush out and buy it if you already own a copy.
