I tend to use kindle ereaders along with iPads for tablets. My wife's iPad 1 is long in the tooth and as she's not picky I was going to upgrade to the IPad Air and she would take my iPad 3 hand-me-down.
After swapping it out twice, the Airs seem to be noticeably yellower than the iPad 3. We do have a Kindle Fire HD and I noticed while the white background when reading is more uniform, it's not as white as my iPad 3 was.
I'm considering just returning the iPad Air and going with the HDX. Does anyone who has both or played with both know if the HDX line improved the "white" factor, especially in comparison to the Air. I like the whites to be very white and so far that seems to be few and far between.
