Both the 13- and 15-inch models of the Series 9 ultrabooks are super thin and pretty lights well. The best part about the ultrabooks is that the 15-inch model is really a 14-inch chassis with a 15-inch screen shoved into it. That sounds strange, but it looks great in person. It’s great to have more screen real estate without the extra size in the footprint.
As for the software, both laptops run Windows 7, as you’d expect. It seemed to run pretty fast on the machines, about as fast as any other computer with an Intel Core CPU.
