I agree to an extent, but keep in mind that hindsight is 20/20, especially on the gyro issue. Anytime there's a new problem for a new device, there's a period of time where facts and evidence come together make it clear that something is widespread. I can see a situation where someone would return a device without visiting all the forums, or even swapping it out in front of the knowledge that a device swap isn't going to fix it.
And regarding screens, there is certainly a lot of that around. However, there are also some pretty bad screens at times. It's not a simple black and white matter that they are all acceptable.
