The problem with a lot of the people who post on here is that they demand perfection and justify it by saying they are paying a premium. Sadly 'perfect' doesn't exist and even the exact same devices will vary from one to another. That's why you see people on here returning a product time and time again and still not being satisfied, while others get just the one and say "mines fine!"
Now I'm a pretty OCD person myself and in the past if I had a slightly yellow screen rather than a white one it would drive me insane. However over time I've changed and these variations don't bother me anymore. They are not faults, they are variations. Now if a button didn't work or there was a big scratch, then THAT is a fault.
So rather than scouring threads on here looking for 'variations' that I wouldn't have otherwise noticed, I just laugh and back out of the thread rather than wasting time obsessing.
At the end of the day, steer clear of those threads for your own sanity. USE your product and enjoy it. If there is something GLARINGLY wrong with it, have it replaced. However, constantly striving for the perfect product will leave you frustrated, angry, and you will have wasted a lot of time and energy you could have spent on your loved ones or just enjoying life.
Nothing is perfect. Bought a new car? Look hard enough and you WILL find SOMETHING wrong somewhere.
Its not worth it, stress can be a killer, kick back with a glass of wine (or drink of your choice) and actually USE your iPad/iPhone rather than giving it a full examination or measuring battery life lol.
