Can you explain why the pixel is so much better than the Retina MacBook's screen? My retina is by far the best screen I've ever seen, but I've never had the opportunity to use a Pixel.
FWIW, I've never had any burn in issues with my first gen Retina MacBook in all the years I've owned it. Although based on many of the complaints I've read, that's because I was lucky to get the better screen.
