Adobe DRM on linux recently got a lot better: https://superuser.com/a/1775619 Copied for posterity: --- It's now possible to do this 100% within Linux, without running any emulators or Windows software, even though Adobe don't care about Linux support. Knock is no longer maintained, however apparently it was just a wrapper around libgourou which is still maintained. Installing libgourou (on Arch Linux it can be found…

I figured out how to remove Adobe DRM on Linux just to be sure I can. But, to be honest, I just circumvent the problem entirely these days.

Something about a service problem.

I've had a kindle for years now. A while back I jailbroke it and stuck KOReader which has been so awesome. (Custom fonts? Yes please! Gestures for going to the TOC or bookmarks or back in history? Absolutely!) Problem: it was a lot of work getting my kindle to this state. I'm terrified to turn on WiFi for fear Amazon will send an OTA update and nuke KOReader from orbit. So, when this kindle dies, I am thinking I'd li…

I've got a Boox Note Air2 and it's amazing. Android, can send books through bluetooth, has a shop (that I've never used) and can install Android apps.

Also the screen seems huge and the weight is pretty good. I even got it with 25% discount :-D

Halving the DPI in each direction (vertical and horizontal) means you end up with only a quarter of the pixels: 0.4 megapixels instead of 1.6 megapixels.

IIRC these panels are 150 DPI color, which means it's less than halved in each direction.

I thought they were 300dpi panels, but that the dpi was halved in color mode? I'm curious what color filters they have. Perhaps each 2x2 pixel has 3 filtered dots (RGB) and one fully transparent dot?

E Ink has been developing a full color tech they call ACeP. This tech has no color filter like Kaleido 3 so can run at full resolution and better contrast. Wonder if this tech will reach ereaders soon. Rumors are that Amazon is considering ACeP.

There was one on the market, but not from the well-known names: the Bigme Galy. Doesn't seem to be available anymore though and Bigme's site has no mention of it

I have very little to add about the color aspect, but I can say that I love my Kobo. I've had three Kindles before buying the Kobo, which I got because it has a "better" integration with my local library (better in quotes, because I still have to do with the Adobe DRM, which is so bad on Linux that I borrow my wife's computer just to transfer). The Pocket integration is fantastic, as are the physical page turn button…

re: the library integration, I'm confused about how you or your wife's computer is even involved in the process. For my kindle I borrow books on libby and amazon magically beams them over. Does your library not use libby? Are you taking extra steps to avoid amazon?

FWIW, we bought an arm to hold the kobo up while we’re reading (one of those smartphone holder things, they’re a dime a dozen) and a little device that clips onto the kobo. It comes with a remote, and you can turn the pages with it by making the kobo think you’ve touched the display with your finger. Best 50$ I ever spent (arm + clicker). Now I can turn pages while in bed without holding the kobo and with both hands…

Please link or provide a product name, I've been looking for something like that!

This is like optimizing a horse and carriage for modern era. The price is nearly that of an iPad mini with vastly fewer applications.

Here's a current-day horse carriage that costs as much as a cheap engine vehicle: https://www.carolinacarriagesuperstore.com/product-page/bran... Same price, fewer applications.

And runs a lot longer on a battery charge.

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 ju…

Almost sounds like Pixel Qi, the display tech for the olpc project. Did anything behind of that tech?

This is eink while Pixel Qi was transflective LCD what is sometimes called e-paper. Transflective displays are used for some smartwatches, Garmin ones have long battery life with them.

FYI I've been running multiple jailbroken Kindles connected to WiFi with KOReader for a few years now. Just install renameotabin and you're good to go. You can even register it like a normal Kindle.
