Sure e-ink was amazing when it first started and now with 600x800 readers like the Kindle and Nook, I think it reached it's end-of-life. Anything higher than that would make the user wish he could run videos and photos. And for the Skiff Reader, 1200x1600 is amazing, but at that resolution I want color! It's like having a black and white LED TV...

...that is all.
