I've had my S90 for a few years of active outdoor life and it seems to be doing fine. At times, I thought the below zero temps I sometimes use it in would cause problems but - no.
As with most of my point and shoot cameras, I bought a refurbished model on Amazon for a substantial savings with the same factory warranty.
