I got it replaced because the microphone has stopped working. I thought that my original iPad's screen was perfect, but this one is even better. Every white area is perfectly so, even with the brightness all the way up. Before it had shades of pink and green that didn't really bother me, especially since almost every iPad had this issue.
TL;DR I didn't realize how perfect the retina display was until I recieved a replacement.
