The Nook HD features a 7-inch display (1440 x 900 resolution), a dual-core 1.3GHz processor, 1GB of RAM, expandable microSD storage, an 11.1-ounce weight, and advertised battery life of 10.5 hours of reading and 9 hours of video. In its publicity materials, Barnes & Noble didn’t exactly pull its punches against archrival Amazon, claiming the Nook HD is 20 percent lighter, a half-inch narrower, and armed with a sharper-resolution screen than the Kindle Fire HD.
