And yea, Samsung isnt that great, but it all depends what you want to use it for anyway. It is probably perfect for you. The same goes for Asus. Though I would say with Asus you tend to get way more for your money. (My last computer, while crap, was Asus, and it could play a lot of high end games, and was only 300$.)
Yea, laptops are pretty pointless to repair. Because all the pieces need to fit in a certain way, it just makes it really hard and expensive to find the right ones. A reason i use desktops, but I also don't need that mobility.)
