Canon IXUS is a series of digital compact cameras made by Canon. They have been pocket sized all the time, the main difference in size between the older and the newer models is that the newer models are slimmer. If you wonder about whether you should get a new or a used one, you could go for a
used one if you don’t need all the mega pixels you get with the newer ones. The newer one also have bigger LCD screens but the optics don’t seem very much better, so you will get nearly as sharp pictures for less money.
I have a Canon IXUS because of the size.
I usually use a digital SLR,
