What are some good laptops for chemical engineerig?

<p>I am currently a junior majoring in chemical engineering, I had a compaq for my freshman and sophomore year; but I think I am gonna need something a little better. Any suggestions
I am looking for something in the $ 500-800 price range, I will more than likely buy it off ebay!</p>

<p>I was actually considering the Toshiba satellite, is that a good laptop?</p>
