This is a very neat looking and sounding machine, the Samsung Series 9 is thinner than the MacBook Air at the thickest point and thicker than the MacBook Air at the thinnest point. It costs a touch more and has a few hours less battery life. It is faster on paper and the screen is much brighter. Windows slows it back down to being slow than the MacBook Air.
What intrigues me about this machine is that for a first rev ultra-portable is seems to have done very well. The speed tests are based on Windows performance and thus are likely to remain poor. If they get the resolution bumped up to match the 13″ MacBook Air, Samsung has a great option for frequent Windows travelers.
