I never would have bought one of those Kindle ebook readers… but now that i got one PaperWhite from eBay for 100€ i must say i am impressed.

The Battery lasts basically „forever“ and with forever i mean: 3 months depending on usage – which is largely attributed to the monochrome screen that turns off automatically when you close the cover. btw: there is no OFF switch. which is Orwellian 1984 kind of scary.

Yes it only has 1x CPU Core X-D (how can things run smooth on one CPU core? unless they are written in Assembler)

It also comes with WiFi and a microphone (!? why does a ebook reader need a microphone?) this is where the surveillance paranoia starts… you COULD hook it up to your Amazon account… and have Amazon know ALL the details about you.

So i decided to reset the thing and not allow it to access the wifi.

The intergration with Linux is pretty smooth.

I was able to simply USB cable hook it up with Debian 8 and CentOS 7 and access the internal memory (2GB) like an USB Stick.

While the Kindle can read all kinds of formats (TXT, PDF, unprotected MOBI, HTML, DOC, DOCX, JPEG, GIF, PNG, BMP through conversion, AZW3 (Kindle Format 8), AZW (Kindle), PRC natively) there is also a pretty cool eBook management program called Calibre that also can convert eBooks from / to different formats.
