When I play a game or have an application running a black-fullscreen image I can see faint blue light streaking up from the bottom of my screen. The bluish light fades away after about 1 1/2 inches, but is noticeable. This is occurring on a 2-week-old base 13" 2011 MBP. Edit: Found a thread on this topic that thoroughly explains the problem. Has to do with backlight. http://forums.macrumors.com/showthread.php?t=1106571 I take it this is normal and to be expected?
