which laptop

I'm thinking about getting a laptop. I would want one primarily for college stuff. Like word processing. I would prefer to be able to play perhaps some less demanding kinda old games if possible. I don't mind OS much. I've never used linux but as long as it does basic stuff i don't think i'd mind, that or XP. However my main concern is battery life and price. I want to get a laptop for the cheapest price for the longest battery life. I don't need a power machine so I was wondering if anyone had any suggestions.
