We all know that not every phone is perfect. I don't think you're talking about that. Reasonable people have reasonable expectations.
I've replaced mine once. Not even my request...walked into my AT&T store to show my wife something...and the guy that sold me the phone asked to see it. He did something...and said, let me replace it. Apparently the vibrater was loose,,,or rather, more loose than it should be. I didnt notice it.
I did not have data connect issues. The purple screen impacts me only if I switch to low light...which I do not and most likely never will do. I do have a wifi data issue...but the impact is rare.
The guy next to me at work has the Titan II. He likes it...but its too big for me. I can tell he's not way overjoyed with it....but it suits his needs. We both work in a place that does Mobile software....so we both know our phones have a shelf life of...until the next big thing.....so most problems, for me...are almost always liveable....
