My first 5D II mirror broke and canon replaced it under warranty. The second developed a half dozen dead pixels at about 1.5 years. The third never downloads the last picture taken, until you take more pics then it will download it as the first pic of the next series.
I went through 4 - 24-70 II's before I found a keeper. I am still waiting on the 36mp 1Ds IV that was rumored. My 16-35mm can't withstand being dropped 4' without breaking.

On a side note I am debating, would the 5D III be a better wildlife camera (not BIF) than the 1D x. I am upgrading lenses to.

And the measure of a company IMO is do they stand behind their products. I am not sure how Nikon arrived at this point but it looks like they are passing the stand behind their product test.
