I've owned Carta (I took it back) and Pearl screens. The Carta upgrade was no big deal, no matter what the advertising specs say about improved contrast. But I will say the carta screen was on a lighted screen, which tend to be less constrastful than non-lighted screen.

But for manga, or doing anything else other than reading straight normal books, software is the key. You can have a great peice of hardware, but if the software is inflexible / limited, you are limited in terms of what you can do with it.

Re: Koreader, yeah, I see your dilemma. Look, I have a Kobo Aura HD. I tried Koreader and Coolreader on it. They're okay, but they will never compare to the flexibility of software Android offers. Ever. They are attempts by a few part-time coders to increase functionality on linux-based units. They're noble efforts can never compare to the incredible array of professional software to be found under Android. Forget it. No comparison. But remember, Android software designed for a phone or tablet might (and often doesnt) not work well on e-ink. You need to check with Onyx users what will work.

I think you need to do some research. Look at how well Koreader works with manga, especially on the boox. Ask in the sub-forums about other people reading manga on the big Onyx. If you're going to go with Koreader, make damn sure it will work for you, because it might be you're only option on the boox.

Nuff said.
