I was playing with my new laptop, Fujitsu SH760, i5.
Although it has a 13.3 inch display, it weighs only 1.6 kg.
However, battery life is not that great. About 3 hours.
It comes with Windows 7 Professional. I spent some time trying to come to terms with some of the new features. The taskbar and start menu for examples. The overall learning curve is much lower than I needed to switch to Mac.
