well, they are dell owned, but I think that Alienware still is an independant company that does their own thing. I know because I had many blow outs with them in the past.
You know that clunky big 17" laptop they made with a p4 in it? I owned that one,,, I actually sent it back 4 times for repairs.
2 years later... the gave me a $5000 credit on heir website to buy whatever I wanted. I wound up buying those 2 laptops, a 24" dell monitor, linksys signal booster, alienware bag, games, accessories and more....
I hated these people, untill now. Now I am finally a satisfied customer, and their products have drastically improved. If its dell's mingeling that made this company better, then go dell!
BTW, I also own a Dell xps 710 quad core with an nvidia 8800 gtx and physics processor, and the new alienware laptops dont suck for gaming at all in comparison. I play Lord of the rings online on it at work, and it looks and runs great.
