Alienware is way too expensive in my opinion. From what I heard, Alienware used to buy laptops from Sager ( http://pctorque.com/ is a good Sager site ) and paint them and sell with another $1,000 added to the price.

How much performance do you want? And battery life? For the same price as that Sentia, you can get a faster, more powerful, but hotter and more power consuming Sager. I haven't seen very many people with Sagers, but from what I've heard people are satisfied with them. But I have also seen some people enjoying their Dells, and although Dell had problems a six months ago or so, I think the issues have been fixed, but from what I've heard the support and repair stinks and is dirt cheap, so if you do have issues with a Dell, you are screwed. But otherwise Dell isn't bad.

But Sager are said to just rock. Especially if you think Alienware is good.


Edit: From the looks of things, Alienware still paints Sager PCs...
