I had an AlienWare product for a while, and it worked just fine for me. Laptops are quite heavy, but I never minded about this. After several months of usage, my girlfriend spilled a huge amount of water on it, and it hadn't recovered from it. Not sure if I will buy another one here. Anyway, before this incident, everything worked almost perfect.
Just think about it... Who nowadays can trust ratings of a web site like this? People love different movies. In a past few years everyone just stopped looking for reviews or ratings because it has no point anymore. You like something - you watch it. It's all simple.
