My 3rd one. Apple genius said if it is the color issue, no more replace. I said no. They finally replaced it with a very good one. Here are some tricks: 1. Find a good displaying iPad in apple store and put your iPad above it. Set same brightness and same view (I used the "general settings" page). Show them the difference. 2. It seems the iPad manufactured in early stage is better. They replaced mine with the one manufactured in week 2 in Jan. And it is great. My first one was manufactured in March, my 2nd one was in Feb. Be picky and good Luck!
