As an owner of the S110 Power Shot I was pleased to discover that operation ease had been improved. The compact size was a factor for me in the purchase along with the 10MP feature. It is less like a box and fits the hand very well. The one dislike I had was that it came with a small amount of memory only good for two or three shots. I had to get a 1GB memory card/chip to make the camera practical. But this was easily over ridden by the primary features I like, namely small size, large MP and ease of operation.
