In January 2010, Pogue reported that Barnes & Noble claimed its Nook e-reader weighed 11.2 ounces, though Pogue found it weighed 12.1 ounces. He wrote that the discrepancy was "a rather important fib in a product that you have to hold in your hand for hours at a time." Barnes & Noble claimed that "higher than anticipated demand" for the Nook created "minor variances in the manufacturing process" resulting in a "marginal weight difference…making Nook 12.1 ounces." The company said it would update all references to the weight.
