Bests & Worsts Reviews from Amazon

On the last day of my trip to Costa Rica I clicked the shutter on a Canon G9 and it beeped several times at me. I tried again, same response. I checked screen and it read "Card Locked". Back in the car I tried everything from setting and unsetting the little lock tab to a new battery. I couldn't display any of the 100 +/- photos taken, shoot anymore, or even access functions like "format". Back home neither of our computers recognize it as a device, and my wife's camera simply says "no memory card" when I try it there. All photos are lost and I am returning this "dead piece of plastic" tomorrow. I would love to see some statistics on how often this happens and if any brand is more reliable. Trip was great otherwise.
