This is talking about the 2011 Quad-Core MacBook Pros. Several reviews (Engadget, Anandtech, Laptopmag, etc.) have stated that they have gotten anywhere from 7.5 to 9 hours of battery life with Wifi on, screen brightness at 50%, backlight keyboard off, bluetooth off, etc. doing non-flash web browsing. Has anyone else gotten this kind of battery life consistently and if I purchase one of these can I consistently count on it getting this kind of battery life in Microsoft Word + non-flash web browsing?
