I'm interested in getting a macbook or macbook pro for college. I would be getting the macbook pro 13in. What i would like to know is what is the battery life like on the regular macbook and the macbook pro. Apple says they both get the 7hrs of battery but i would like to know what the real life battery is like not what they say. The basic things that you would use it for. Browsing the web? Watching a movie? Typing up document?
