i think he lost his alienware, his dad changed his mind about giving the alienware to him and he was grounded for a month because he did something bad =D kidding.
anyway, alienwares are still better than local laptops that you get for 300$, i dont even think thats a laptop anymore but a netbook. so keeping it wont do you bad, just reformat the OS clean and install only the necessary files.
buying anything more expensive than the alienware would do you worse than keeping the alienware, because you`d pay a greater price just to get a few more percent of performance increase, something like buying an i5 for 600$ and buying an i7 for 1200$ but the difference is miniscule(about 50% average performance difference for 100% more to pay).
