Building your own is interesting, but probably way outside of my skill set. One of my concerns was the repairability of devices like the Kindle and whether or not you could replace the batteries in them once they die. I suspect it's probably not possible, but I should try to find teardowns just in case.

I didn't know about the Kobo brand. It does seem like there's a better second-hand market for them so I might price watch them on ebay for awhile and see if I can get the h2o model. Though that github says the okreader may not be compatible with the h2o models.

I figured you could just avoid connecting to wifi to avoid the botnet, but I've read the water proof models have cellular capabilities which turned me off a little bit since I don't think there's any way to permanently disable that with 100% certainty. I don't think the Kobo e-readers have that so perhaps they're the better choice.
