Bibin's laptop suggestion text wall v0.8
Dell's latest run of laptops seem to all have the same terrible trackpads that seem to refuse to move unless your finger has been down about 0.6 seconds, which produces a noticable lag when you want to just move a tiny bit. I recommend against dell.
I recommend so hard for a ThinkPad. Honestly, I suggest a T61, when IBM was still involved in development. The newer, lenovo only ones I've not liked as much, in terms of build quality, specifically sturdiness and the keyboard. The X series, like the X60, may be just right for you. It's got a solid processor, HDDs far above 40GB, and is very light (< 3 pounds), and 1" thin. You can have one for about 400 on eBay used, less if you get lucky.
As for HP computers, personally, I don't like them - they tend to get quite hot, the style is very shiny-plasticy, and the glossy screens are a disaster. They do tend to have decent speakers and keyboards, though, but the mouse leaves a lot to be desired. I don't recommend these hulking mammoths, but they are not too bad for not-so-mobile laptop use.
Don't get me started on Sony.
Asus is pretty rock solid. I am not that fond of the style, but they aren't too wannabe-flashy, and from experience with asus motherboards, I can say I've liked their performance. Check out some of their notebooks if you want pretty good stability and battery life.
Maybe even consider getting a used MacBook Pro - even the oldest, slowest one is a little faster than what you need, and you can get one in good shape for under 700 easily. It's simple to upgrade the screen to be 1920x1200, should you want that, and it's a very solidly built machine that is very flexible in terms of what operating systems you can install. Mine, for example, runs Mac OS X Snow Leopard, as well as Windows 7. The keyboard is fairly good, too, and the backlight for it is a feature I didn't expect to like so much, but it is useful in the dark.
See? I argued for an apple computer without fanboy points. Those are valid points. Not participating in a war.

Dell mouses rock my socks off though, they're awesome.
Dell mice are rebranded logitechs.
