Know that while useful in some scenarios, I'd avoid buying a color e-ink display if you're still going to primarily be using it for B&W colors.

To quote the eBook Reader Blog [1]:

> The main drawback with color E Ink screens is they look darker than regular B&W screens because of a color filter layer that is applied over the top of the screen, which makes the contrast appear lower. Kaleido color screens are really just regular black and white E Ink Carta screens with a fancy passive filter over the top (that’s why color resolution is lower than black and white resolution).

there have been color ereaders for over a year now...

And when Ford launches a new model, do you respond, “we’ve had cars for over a hundred years now…”? It’s a product announcement, I see no claim that Kobo invented color readers.

Bleh, and I was just up until 1am last night reading about black-and-white PDF compression schemes for my Kobo :) Technical knowledge obsoletes so fast.

(Well, maybe not that fast: ImageMagick's best-performing monochrome scheme is, apparently, one that was standardized for literal fax machines in the 1980's [0]. A very basic one called "Group 4").

My experience with ebook readers is as follows: I read mostly scientific PDFs, with formula's, graphs, etc. First I tried the Kindle - it was completely useless because of screen size. I went for PocketBook Inkpad Lite - the page size is more or less fine, but the page turn delay is noticeable. It's so subpar to the real book when you can just browse through pages quickly. Finally I picked up the biggest Chinese tablet I could find (Doogee T20 Ultra 12") and it is the best experience so far except one thing the screen is glossy, not mat, and it affects my reading experience. E-ink ebook readers are perfectly fine for prose etc.
