What is the point of adjusting your aperture if your camera is a point-and-shoot? Seriously, even at f2.8 (2.8!), the depth-of-field is way too thick 9 times out of 10. I leave mine on 2.8 almost constantly, unless doing a landscape. So what point, really, is there of adjusting aperture when its in a range that's practically unusable (really thick, to infinitely thick DOF)?
