new Intel Core i7 mobile processor. One thing you said in the same sentence was battery life and backlit keyboard. Those sort of contradict each other. There really aren't much difference between laptop batteries. The things that seperate different laptop and battery life the components that use power.
I'm a first year engineering grad student and I'm trying to decide what new laptop to get. I've had a Dell Inspiron 6000 for the past 4 years and I've had a pretty good experience with it, but I don't think it will last much longer. I want something smaller and lighter (because I carry it with me everyday) but it still needs to have really good performance because of engineering software (like MatLab). I'm seriously looking at the Dell Studio 14z, Dell Studio XPS 13, Sony CW, Sony SR, or maybe a Thinkpad T400. Does anyone have any experiences with these laptops and have advice? The only computers I've ever had were Dells and I love their service. I've heard that Thinkpads were supposed to be some of the best performing, but they are just so unattractive (but if the Thinkpad is that much better than the others, I'll still consider it) I don't like the glossy touchpad on Hp's.
Graphics dont really matter much to me, I won't be doing any gaming on my laptop. I mostly browse the internet, use office, read a lot of pdfs, and use MatLab, MathCad, and possibly Labview. Good battery life would be helpful, as would a backlit keyboard.
