I scored a refurb 2:53 MBP early last month and while I love it, the battery only gets me about 3 hours on a full charge, and that's non-cpu-taxing usage (IE web browsing via ethernet, Word etc, no wi-fi, no bluetooth). This is on the 9400, not the 9600, with screen at roughly 50% brightness. Does that sound right to you guys? I thought it would get me at least as much time as my 2006 coreduo Whitebook gets?
