By now we should all know that when buying an ultra portable notebook, sacrifices almost always have to be made but ith their new U36SD, ASUS is turning these preconceptions onto their heads. Note only is this new laptop equipped with a standard voltage Sandy Bridge processor and a dedicated NVIDIA graphics processor but it weighs less than 3 lbs, boasts over 7 hours of battery life and comes in at under $900. Sounds like perfection, doesn't it?
