After extensive research on laptops I choose Asus. Obviously new in laptop segments. But after many R & D I feel that prices are also less competitive as compare to other manufacturers. Product quality is quite good as per value of it. It comes with original windows 8.1 which is up-gradable to widows 10 free of cost. The only concern is that no CD or DVD for drivers and original windows not comes with it. I hope in future company will take care of this. So at last I prefer to buy it.
