iPad display polarization disappearing display problem nothing new (video from June 2010)

I was surprised to see this “news” item appear in ZDNet a few days ago: iPads go black in portrait mode with polarized sunglasses. This problem has existed since the first iPad launched in 2010. You can see a video demo of the problem that I posted back on June 5, 2010. What is surprising, however, is that Apple never fixed the problem in the next two iPad generations.
