The Emergency Camera Is Still Working

My "emergency" Canon PowerShot A3100-IS pocket camera which I still manage to use when I'm at work, has definitely seen better days ... The shutter only fires when it feels like it, the lens has more than it's fair share of scratches and now the SD card keeps reading 'error' and has to be taken out a put back in before it works properly ... That said, however, it can still capture the moment when I don't have my other cameras to hand ... and at least if I accidentally damage it whilst at work. it certainly doesn't owe me anything ... :o)
