A warranty can be a good thing
I purchase my Canon G-11 in late Fall 2009 at Best Buy. It's a high end P&S camera, so I take out a 2 year warranty on it mainly because of the higher purchase price. During our Oceana Palms visit this past February, I notice a problem with my toggle ring which controls my manual adjustments for focus, aperture, and shutter. I finally take the camera to BBY ( Geek Squad ) for a look see. They determine that they can't fix the camera. My mfg warranty has long since expired.
The good news is that my extended warranty offers me a "comparable camera" in exchange. Since Canon no longer manufactures the G-11, that made my 'comparable camera' the Canon G-12 ( which is the exact same camera as my injured G-11 with a few new "tweaks" which improve an already great camera ). So the moral of the story is that an extended warranty can be a good thing for a camera when the camera costs more than a couple hundred dollars.
The only glitch is that the store does not have a G-12 in stock and I've gotta wait until Wednesday to pick it up. But because the G-12 is virtually the same camera, my G-11 batteries also spec to the G-12 so my total out of pocket expense is the cost of a new two year warranty for the G-12. The camera manager at BBY tells me he rarely sees any warranty issues with the Canons BBY sells and I agree that that Canon is a sound product and my faith in the brand remains untarnished.
That said, in addition to my manual operation problem with the G-11, I also began to notice a few dead pixels a couple of months ago. Dead pixels ( more precisely "hot" or "black" depending upon whether the bucket is stuck in the on or off position ) are not an unusual occurance on camera sensors and they are most usually unnoticable in normal sized prints. I myself discover them when I was doing my post-processing in Photoshop last month as I work in full or 75% resolution and I happen to discover one dead pixel and this prompts me to search for others. All told, I find 3 which are not a big issue. But being the curious guy I am, I note their specific location and I backtrack through my image archives to see when the problem first appears. Turns out it coincidentally begins during our February trip and that by the second week, two of the dead pixels regained their function. Could not find an evidence from my earlier archives, at least for those specific pixels. Just another way to waste time with your camera and computer.
