Well, when I purchase this laptop it was about 46000 yen cost, the cheapest yet most powerful laptop I really want. Likes its wide screen make me easy to do work such as photo and video editing, some code programming as well as typing by dividing the screen into two panel. it work fine with some old PC game since im not try to use for hi spec computer game yet. as far as i use it (for more than 1 month) it work fine no such error or malfunction. in some case, the battery make me a little disappointed because it only last for 3 hours with full charge. Its not really good for mobile use while the weight is not to heavy. I think the material used is plastic more than metal material. OK thats all, thank you
