      How else are you supposed to read manga if they don't sell it in my country? Import the Japanese version that I can't read for 20 bucks? Read it on a computer screen burning my eyes? Fricking delusional

          And one with color, since every 20th page is a color page. But mangatards simply need to realize eink is for books.

            That's going to depend on a lot of factors.
            In volumes, a common approach is to have 4 color pages in the front, out of 150-200 in total. You can easily view those on a color display instead. Many publishers don't have color pages in volumes at all and will convert the color pages to greyscale, even in digital versions. A small number of publishers will also include color pages on the inside, at least in the digital version.
            In magazines, depending on the specific one, you'll have color pages in the middle. Digital magazines will have extra color pages but those are repetitive.
            Web manga tend to have some shitty color label on the front of every chapter. A couple of digitally published series are full color.
            Disregarding full color and semi color releases, the highest frequency I've seen is Gochiusa with 2 color pages for every 8 page chapter.

            It's either one in 20, one in 40, or more than one in 20. It doesn't matter. ereaders aren't for manga. I personally would just use my LG OLED tv to read manga on and spent most of my time reading real books.

            I don't understand how you reach those numbers. Outside of 4koma, most series are 20 pages or more per chapter and only very few series get color pages every chapter. Many don't get color pages at all. Print magazines have 0-3 series with 1-4 color pages out of up to 40 series/1200 pages.

            From what you say it sounds like you don't read manga at all.
            Here's the new Weekly Manga Times issue, note how only Kowashiya Gen has a color page even though the magazine has 220 pages.

    Anyone know any script/tool to convert scanned PDF images into more e-ink friendly format?
    Some PDFs are just scanned pages, the obvious way would be to OCR it, but the text isn't easily OCR'd because of language support.
    But I was thinking what about smart vectorizing tool?
    Like converting it to svg and repacking it?
    That way it would refresh only the text part.

    For the 7" segment it seems to be going entirely to color unfortunately. Both Pocketbook and Boox have made their own color e-readers.

        I agree, all we need now are high resolution Carta panels that are actually large. I'm tired of 10" and 13" panels being 200ppi.
        Color would be cool if they continued trying with Gallery instead of doing Kaleido, which is the worst of both worlds.

          Gallery was the worse of both worlds. The colors were still washed out and it was a lot slower than the regular panels.

      >if it actually delivers on no blue light claims
      What do you mean? It's a transflective display. If you keep the backlight off, it won't emit light in any wavelength, only reflect whatever light is incoming. The backlight is amber so it shouldn't contain a whole lot of blue.
      The main issue should be how well it's actually usable without the backlight since RLCD tends to be a lot darker than E ink.
      The price is also a lot worse than an E ink tablet of the size. I don't really see the advantage. It's still monochrome so you can't really watch videos, play games or whatever else people want faster refresh speed for.

    I've been considering an e-book, but would also really appreciate the useability of a windows tablet. Is there any reason to have a separate e-reader and tablet? Because I feel like just getting the tablet (lenovo ideapad duet 3) would be simpler...I'd have windows, would be able to use basic programs, but also would install SumatraPDF and would have all of my books on there too. What's the benefit of having a standalone e-reader, no blue light and better battery life? Genuinely asking because currently I have neither, just a desktop and a 17" laptop (want a smaller device, but bigger than my phone and good for reading)

      Battery life depends on whether you get a BSR device or not. BSR solves a lot of ghosting issues and allows working in faster refresh modes but drains the battery.
      A big benefit of E ink is that you can perfectly use it in bright conditions, for outside usage it is second to none.
      The 300ppi screens in 10" have a lot higher resolution at 2480x1860 compared to the Lenovo's 2000x1200. The aspect ratio also works better for documents.
      You can get a lot of functionality via Android applications. It may not replace everything a desktop OS can do but still can do a lot more than just open books.
      E ink also tends to be lighter than LCD. The Boox Note Air 3C is 430g and the Go 10.3 365g. The Lenovo Duet is 600g.
      The Lenovo also uses a shitty AAAA powered pen instead of the more usable Wacom EMR tech.
