Do you call that a constructive response?

FWIW, I was dead serious. For the vast majority of applications, an e-ink is entirely adequate. With the very few exceptions (such as video or games), all that a mobile phone - or indeed any computing device - displays is a static screen with no fast changing areas. On a battery powered portable device, the power saving and sunlight readability of an e-ink would vastly outweigh anything else.

I do realize that some people may like watching videos on a mobile phone and for them it might not be the best choice which is why I said I would pay extra for the option.

But the entire discussion is purely academic anyway since Chen lost my custom the moment he said he was going for a large screen and refused to budge. There is absolutely no way I am buying anything above 5". I want a portable device. One that fits comfortably in the hand and pocket. Not one that I need to carry in a backpack. I already have a few of those.
