I have to assume that the folks who have had problems with this camera either have not completely read the manual that comes with it or are too quick on the trigger for shooting (all digital cameras need a second to focus properly before fully depressing the button), or they received a lemon (which is why companies provide warranties) and they should have either return the camera to Amazon, as defective, for a replacement or to Canon for fixing.  I have found Canon Service to be Excellent over the years.  I have used them on a couple of occasions.  On one, the camera was well over a year out of warranty, the cost to me was going to be about $149 to fix.  After they received it, they wrote to me that this was a component that has been failing, and should not, and thus there would be no charge for the service.  Now, I can not ask for a more honest, customer oriented manufacturer than these folks.Now, it is true that because there is a "popup" flash, I needed to learn to hold the camera differently.  The way Canon suggested is Great as it gives me, and the camera, far more stability than the old way. I did use my left hand finger on top of the camera in a pincer hold with my other fingers.  Now, it is cradled in my left hand between my thumb and second finger with the first finger cradled along the side of the lens giving me far less shake.  By the way, this flash sure does light things up far better than my other cameras with the built in flash on the front!!!Thus far, the zoom shots have been awesome, everyone is raving about the quality of the pictures I have taken of them,, Low light shots are unbelievably clear as if I was using a flash and the day shots are great.  This Powershot S90 is a super digital camera.Thank you Cannon for a Great Camera.
