so far as brand its as others have said, none of these makers manufacture components, and even if so they share them sometimes. sell to one another. a computer is kind of like a car like that, only even less so. most builders use the same components as the other and source them from the same places. quality control still comes into play, build quality, and customer service. and lemons do exist. but Dell / HP / Toshiba / Asus etc are all pretty much the same quality wise, all other things being equal. i have an HP Probook and its reliable and built tough. but so are others
so far as this computer, it is nothing special spec wise. if you want a 17in screen and that is a priority its a good deal as its a fairly nice screen to watch movies and vids on. but the processor is capable but average (its a detuned first gen core i3 330m), the ram simply adequate, and the HD small by todays standards. if a person looks around they could find a 17in laptop for $60 more with a better display, bigger hard drive, modern processor, better graphics, and long battery life thanks to its low power draw, cool running processor. which is important in a 17in laptop. and its new

now if encoding video, music files, unpacking large .rar files, or doing any sort of intense computing otherwise, neither the lappy offered on w00t today or the one i linked would be your choice, and the w00t offered laptop is stronger in those areas. but for everyday use for Windows, internet, videos, light multitasking, email, and even games because of its better graphics. most any AMD Fusion cpu will be better for multimedia (mainly HD video decoding) than the intel B940 due to the B940 not having hardware decoding capability. for pure-CPU tasks though, the B940 will be faster. but thats not what many if not most users do with their laptops unless always on the go. when i want computing power i use my desktop. so imo the walmart offered laptop is a substantially better value now and in the future for the average home user. longer battery life, bigger HD, better graphics, cooler running, display just as big and at least just as well if not better
unless you want to save $60 buying a refurb. and that is fine, too
