I have never seen or heard of an epaper display wearing out but I don't know of anyone who has tested. I'm tempted to grab one of my spare screens and just hook it up to an arduino to constantly refresh it.
I hacked an old Kindle DX to run a screensaver, swaps out a full screen PNG about once every 30 seconds, been going for several years without a hitch.
I have been very happy with my ReMarkable 1, and have ordered the ReMarkable 2.0. Hacker News might be interested in the active development community around the device: https://github.com/reHackable/awesome-reMarkable The device is open. It's just an embedded linux device. You can ssh into it, and run arbitrary code. The SDK is based on Qt. You can also connect a keyboard to it over a USB-on-the-go port. I have been…
I contacted their support about the openness of their device. This is their response in case others are interested: Aug 28, 2020, 3:44 PM GMT+2 Hello there. Users can gain root access to the device by using SSH, so the device is open for developing your own software. The GPL and LGPL version 3 requires us to give users access to their own devices. It's part of the anti-tivoization clauses in the licenses. A lot of ou…

Um... In my household we've gone through seven ereaders, used by four persons. Nobody has ever been able to bust the screen -- the reason people replaced their ereader was because the battery stopped being able to hold charge or the usb port to start wobbling. But the screens were fine, all the time. And e-ink screens are made by one manufacturer anyway.
1st one: Kobo Mini. Was inside a case and between two books in my rucksack and broke just carrying it home from work 2nd one: Another Kobo Mini. Broke inside the thigh pocket of my combat trousers. It was also in a case and had the screen facing inwards, towards my leg, specifically to avoid the risk of me bumping it against something. 3rd one: Kobo Aura. I had high hopes of this one as, unlike the previous two, wher…
I almost impulse per-ordered the RM2 when I first read about the SD card mod here on HN. I decided to wait after hearing about the limitations as a reader and the slow software development. If you're considering the RM2 for anything other than a sketch/note pad, I highly encourage you to watch this fantastic review from My Deep Guide: https://www.youtube.com/watch?v=4iIAYMsugzM Full review: https://www.youtube.com/pl…
> Things as simple as font resizing are 30x slower than on a Kindle It's not a constant factor. This is best understood as a bug. Here's what the reviewer demonstrated: If you change the font size, then the interface locks up and you can't do anything, until the backend has generated new page images for the entire PDF—no matter how many pages there are. He showed that, while it was fast for a small document, it locke…

I think the question quickly becomes why not an iPad. They're easy and pretty cheap to get hold of, have good screens, lots of people can easily write new software for them and they're also a tablet . Many people may already have one and so using hardware they already have is much cheaper than buying new special hardware. Also, eink screens are nice to look at but so expensive for non-kindle sizes.
I've played so much live music with an IPad, but after the 4-5th time having it freeze up mid live performance I gave up on the dream. It's just not 100% reliable, and nothing like standing there like an idiot desperately trying to swipe to the next page to make your realize how great paper is
chucking the ipad because of that is like chucking the baby out with the bathwater because the bathwater got cold. The baby still has value. you just replace the water.

I'm a huge Polar fan! I'm considering buying an iPad just for using Polar, but I was wondering about the ReMarkable as well, since I like e-ink better for reading. Do you have any recommendations for a tablet to use with Polar?
What app do you use for Polar? I used Polar for a bit on my Mac but gave up because I do most of my reading on an iPad. Would give it another shot if I could get Polar running on iPad.

IpadOS cut pencil latency to 9ms.
That number was calculated by taking a high-speed camera and watching how long it took the line to catch up with the pencil. They cheat on the metric by juicing up the prediction. You can see this by flicking the pencil and then picking it up -- the line will go farther than you intended. And if you change directions, the line will take more than 9ms to catch up with you.

Do you normally draw or write by flicking the pencil? Prediction that increases the speed usefully is not cheating
In general, this point makes me think of computational photography. If you have extra computing power, you can do things that are synthetic, but nevertheless real enough to deliver satisfaction, in real time.
