When considering what price range laptop you're going to buy, an important factor is what type of screen you want. If you are hunting for bargains, beware passive matrix (DSTN / HPA) screens. Basically, they look terrible. The standard LCD laptop screen today is Active Matrix (TFT). Both types of screen are perfectly flat, about half an inch thick, and don't use much power. For passive matrix screens, HPA screens are harder to view at angles, but newer versions have improved greatly from the vague and translucent image quality of old DSTN screens. Still, TFT screens are brighter and sharper than even the best passive matrix screens. LCD manufacturers don't even make passive matrix screens anymore, so if you are buying a new model, you don't have to worry much about that.
