To continue the thread drift in to a conversation we have had before ... the problem with the 787 window 'screens' is that you will not be able (I understand) to open them just a crack. With the sliding screen, you can open it half an inch and then squeeze down in your seat and still enjoy the view.
I gather that when you 'open' the screen on the 787 window, it will be across the full face of it? That means having to drape a blanket over your head to keep the glare from others. IF that is the case, then I think it a retrograde step.
