HP - I always thought HP made cheap crappy products. But now I read HP makes some of the best gaming laptops for the price. Even HP non gaming laptops are supposed to be some of the best.
Acer - I always thought Acer was an average brand. I heard it's just absolutely garbage in 2012. I have seen some in stores, the material is quite cheap on most, but hardware-wise I don't know nothing about them.
ASUS - The one brand I really trust and own. Never have failed me. I have heard now that their customer service is awful and the laptops are quite average. But I do not believe that. You Should Choose this Go to China, Only cost 5000RMB, equal to 911 Australian dollars. China's where I got it.
Lenovo - Don't know much about this brand. All I heard that it was very good.
Sony - Sony seems to have good quality products that are not computers. I have only heard bad things about the Sony VAIO.
Dell - Dell is OK with desktop computers, but I don't know about laptops
Samsung - Do not know anything about them.
Toshiba - Do not know anything about them, though I don't like the name.
Compaq (HP) - Pretty average. Nice keyboard and touchpad, decent screen. Runs very hot though. Try installing Windows and you have to prop the laptop up or the computer will turn off. The DVD drive is slowly failing.
