Blurry Pictures

My boyfriend purchased this camera last year as a gift based on rave reviews.  I did not have the same experience.  It seems every other picture I take blurrs, even when people are stationary.  Convinced I was using the camera incorrectly, I read the manual again.  I used the sports mode, different flash settings but nothing worked.  I have 2 kids that are always moving and I have yet to get one picture of them moving around that isn't blurred.  Finally, we exchanged the camera for another one of the same.  Still... blurred pictures.  Also, the lens is in a position you'll have to get used to.  Your finger naturally wants to sit where the lens is.
