资料：Samsung’s Notebook 7 Spin is a stylish，versatile work machine with power to spare.The 2-in-1 notebook’s performance is impressive，and its versatile folding design is legitimately useful.Unfortunately，the system’s shallow keyboard and lackluster battery life curtail its productivity potential a bit.
The Notebook 7 Spin looks and feels great，with a slim profile and a sturdy design.As the name implies，the system’s lid spins back a full 360 degrees，letting you use the device like a large tablet.The hybrid design is handy for using touch-screen apps and showing off presentations to a small group，even if the 5 Ib. system is a bit too hefty to carry around like a smaller tablet.
The system’s roomy 15.6-inch display is equally attractive，producing sharp images and vivid colors.Other hardware highlights include a beefy 2.5-GHz Intel Core i7-6500U processor with up to 16GB of RAM，a configuration that makes the heaviest multitasking buttery smooth.
