The Nook Tablet isn't the only Barnes and Noble news today. The Nook Simple Touch eReader will receive and update in the very near future which will speed up page turns by 25 percent and extend the battery life.
Barnes and Noble's battery life evaluations have always been tricky, but before they said that if you read for 30 minutes a day, at a pace of a page per minute, the battery life would last two months (with wi-fi off). Now they say it will last for two months if you read an hour a day (provided all the other variables remain constant). [Barnes and Noble]
