Samsung Series 9 (2012; NP900X4B) Review @ TechReviewSource.com
 

Ultrabooks are definitely not anything new. However, Samsung hopes to do better than the rest with their updated 2012 model of the Series 9 laptop, which comes in either 13.3- or 15-inch models. We reviewed the 15-inch one and were amazed by its thinness as well as its internal specs and performance.
