Showyour wifethe variouscameras and see which she is most comfortable with.
I've seen several posts on various forums asking for advice on which camera to purchase for their wife. The most important factor appears in many to have your wife try the cameras. Some wives are immediately turned off by the camera's appearance more than it's performance. In the end, it will be her personal preferences that matter, more than what we have to say on these forums, IMHO.
