It's easy for people to make unquantifiable statements like "dells break down very easily", when in fact all these manufacturers make computers from the same type of standard parts.
The difference you'll find is in the build quality and the service. Alienware has had notorious problems with build quality: stories of computers going out without the LCD plugged in and missing screws, etc etc.
Alienware is also fraught with service and support NIGHTMARES. All this for a higher price.
When it comes down to it, Dell is a giant and it knows what it's doing. It's support may be overseas but at least it exists. And it's quite excellent on email service.
So go with dell over alienware any day.
I really like both the laptops. My only reservation with Dell is that a lot of people tell me that their laptops are not very sturdy and break down very easily. Can some help me figure this out......I have been thinking about this for a while but can't make up my mind
