Ultrabooks are high-end subnotebooks. Although the term has become synonymous with very lightweight yet full size laptop computers, it’s actually a trademark of computer company Intel and has specific criterion. The specifications cover battery life (5 hours or better), height (21 mm or thinner), time from hibernation resume (7 seconds or better) and, as you would expect, and Intel processor.
Ultrabooks are essentially the PC/Windows answer to Apple’s extremely successful (and slim) line of Macbook Air laptops. Ultrabooks and the Macbook Air lineup are both considered significant contributors to the decline in popularity of netbooks (another type of subnotebook that sports a much smaller screen and keyboard).
