Starting with my first Canon Ixus camera. We had bought this at the duty free on my way to New Zealand on our honeymoon. This was the second digital camera that I had ever owned and was a pretty good camera.
My next camera I was kind of forced to get a new one otherwise I would probably still be using the IXUS850. The old camera was no longer focusing when you took photos. It lasted from Sept 2007 till Jan 2013 so it lasted 5-6 years before failing. Not to bad I guess as I stored it under the R1's seat which would have shaken it around under there. Video quality was a bit on the poor side, no HD.
I've retired this camera from use now in 2017.
I started using this not long after I bought the IXUS240, maybe a year or so. Its photos were so good I stopped using the 240.
