The convenience of the Powershot line is hard to overestimate. With the S95, etc., you can put a lot of photography power in your pocket. Unfortunately, those great little cameras can also be easy to lose, misplace, overlook, etc.
Last Saturday I went out on an all-day imaging spree, doing several events and some general street/transit stuff. DSLR in hand, and lenses, batteries, memory cards, etc. in a bag -- and my S95 in my pants pocket. When I got home, my S95 did not come home with me. So, I spent a couple of days calling event organizers, police departments, etc. I also began pondering if there is a Sony RX100 in my future. (That should give Canon pause.)
This morning I got a call from a transit agency. One of their police officers found my camera in a train station and turned it in as found. Reunion is scheduled for tomorrow morning.
It can happen to you! I was extremely fortunate; I really did not expect to ever see the camera again. I also found I was not as prepared as I should have been. Insurance is the obvious first possibility, but that's got drawbacks, not the least of which is a deductible that may not leave much coverage with the lower values of Powershots.
Somewhere I probably have the camera's serial number, but I'd have to do a lot of searching, and I might not have it around here. I had registered it with Canon though, so the serial number is there -- huge help in documenting it with police in recovery.
Anyway, just a word to think ahead a bit. If you've got a Powershot in your pocket, be ready one day to arrive home without it. As the Boy Scouts say, be prepared.
