Samsung U800 is another of ultra thin series called The Samsung Ultra Edition 10.9. This model not only looks nice, but far ahead of both stylistically and functionally, and its predecessor, Samsung U300. Already at first glance, Samsung U800 is different from its predecessor. Enclosure type slider certainly like many users, it is also extremely functional, this is felt particularly in such a thin package. Just pull silver fold up and have immediate access to the keys at the same time not lose contact with the display.
