Two-hundred bucks is basically "impulse purchase" territory, but I'm nevertheless struggling to see the use case here. If you're into maker projects with Raspberry Pis, then I'm not sure what this does for you. It's a Pi already built into a consumer device. Not seemingly a platform for new maker projects. If you want a tablet with a Linux kernel buried in there somewhere, then there's probably a thousand Android opt…

I have a use for this for sure. I got two 400 models for my 3 and 4 yo and installed all the Linux educational software. Recently I started working on my own educational games for them in C and having something like this I can carry around the house to code on vim while I watch them would be super handy.

A surface tablet with a linux image is underrated IMO. They are good and capable hardware and can be had for cheap. I don’t understand why PI is used for a tablet when its purpose is a standalone device with IO capabilities or for experimenting. I went on this path and bought a few linux first devices and while fun they did not perform even close to an consumer device which with the right image (linux) it could become a very good daily driver.

I'm intrigued, which model Surface with which Linux distro would you recommend in the "impulse buy" territory?

I love this concept, I just really want one with an e-ink screen instead. I think there's a great niche for "embedded" devices around the home -- weather readout panels, lighting controls, music player, intercom, etc. -- but glowing rectangles mounted to the wall are just too... glowing. E-ink panels is where it's at, and a Raspberry Pi powering it is perfect. Unfortunately, the only real general-purpose e-ink tablet…

A friend & I have a dream of building an E-reader based on the 10" ED097OC4 E-ink display that was built into the Kindle DX and can now be had for around 30€ (old stock?). Most parts of the stack are conceptually figured out: A Pine64 SOPINE module (comparable to the Raspi CM, but cheaper), a Linux DRM driver based on tinydrm ( https://github.com/notro/tinydrm ) or gud ( https://github.com/notro/gud/ ), as panel driv…

It's a big problem to get active matrix monochrome displays these days, let alone reflective ones.

Hisense sells a transflective monochrome LCD android tablet.

Very likely it's a custom order panel. I would very like to see a teardown.

The whites are still quite bad I can see already, it has no special high whiteness polariser.

Like the ones used in Chitu Systems SLA resin printers(Elegoo, Anycubic, Creality...)?

From first look, they use colour ones.

This looks great! Except that the sizes are not my favourite... a 6" one and a 9.7" one.. I think the ideal size for a small tablet/ebook reader is 8". Also I dislike the huge bezels of the devices, I wonder if it would be possible to make with minimal bezels.

Oh my gosh. I've spent hours looking for something like this, and was never able to find one. Unfortunately they're out of stock right now, but I'll be ordering one as soon as I can. Thanks!

I once bought a small E-Paper display [1] for a Raspi, and was very disappointed with the refresh rate, it was useless. I wanted to use it to display room temperature and electrical information like home power consumption, solar panel power generation and stuff like that, and expected a refresh rate of around 1 update per second. Having it blink and do stuff for around 7 seconds just to redraw the next frame made me…

Waveshare has some displays with really nice refresh rates, I bought a 6" one with ~300ms refresh rate: https://www.waveshare.com/6inch-HD-e-Paper-HAT.htm

I have this on my list as TODO for my kids. Mine will be with:

- 30k mAh battery, instead of 5k

- use of RPi HQ camera (12 MP, not 5)

- 8 GB RAM (not 2) & a 1 TB NVMe SSD

Projected price for above components is ~ $350. I want to introduce them to Linux (they do everything on Windows for now) and by exposing the RPi's GPIO to also introduce them to robotics.

I was really hoping this would be a "bring your own pi" solution rather than a build in one. If it were BYOP then it'd be great for portable devices like field readings (hydroponic nutrient readings around the greenhouse, wilderness env readings, etc) or taking retropi gaming on the go. I feel like having it built in dampens that portability aspect, especially since RPIs are often reused for various projects.

There are exist laptop shells for your pi

With batteries too? Know of the name? The only ones I've seen are the size of suitcases.

They aren't saying that it needs to be $80. Just not 10x that price.

Well a kindle is actually $110 when it's not ad supported and boox is selling a comparable device for $185. So very similarly priced. I would suspect the boox actually has more capable hardware because it needs to run android 10. I don't care enough to check though.

Kindle is not just subsidised by ads, the business model is based on the fact that you are going to buy ebooks. I wouldn't be surprised if the non-ad-supported Kindle was also being produced at a loss, just like the ad-supported model.

You are right that $185 might be a more realistic pricing, but that's a 68% increase over the price of the $110 Kindle so I wouldn't say that they are similarly priced.
