Let me start with Amazon customer service: I'm sure if I have bought this laptop from another store, I would have a big headache right now.  Fortunately, I bought with Amazon which has the best customer service in the world.  But it was not my first choice.  I tried to contact Asus because, after only a week of using the laptop, a white line appeared on my screen (like the one in the picture). But they were so unempathetic with my problem, and so short of solutions, that I decided to contact Amazon directly, and they solved the problem in less than 10 minutes.  I returned the laptop and bought a new brand.  It was very frustrating to see how Asus did not offer a solution to solve the problem for a new and expensive product.
