I've had my mid 2009 model MBP for almost a year now running at 310 battery cycles... ...In no way does the battery last the 7 hours it originally stated. Of course I don't expect it to anywhere, considering my heavy use...but in reality the battery lasts about 2 hours if i'm surfing the web or watching a movie. Maybe 3 hours if the brightness is really low and doing some easy stuff like writing an essay in Pages. .... I don't think they would now, would they?
