Regarding the panning, it will blur just like in the side-scroller gameboy ROMs on eink, but it should still be recognizable enough to do the job much better than using grayscale images. And dithered text actually scrolls a lot better than grayscale anti-aliased text too.

Also, I am tempted to use old pre-dithered bitmap fonts from early laser printers, which use only black and white hand-adjusted pixels for excellent dithered pixel content. I think old laser printer fonts would look great on eink, and they would scroll fast because no gray pixels.

Regarding the "lazy repaint", I would also provide a "Refresh" button for those who are too impatient to wait...

Regarding your English vocabulary, I think that your posts use better grammar and better choice of words than most native English speakers. I would think you are a native English speaker who teaches English if not for your occasional (but rare) grammatical errors unlike those made by native English speakers. The fact that you make the "wrong" errors is the key. CIA training would teach you how to make the "right" errors...
