alt Hacker NewsI’ve got an old DX. The fact that it doesn’t have net access anymore is now a security feature and an anti distraction mechanism. I can load what I want by USB. It doesn’t do epub3 which is a problem, but it does PDFs and conversion tricks are possible.
The Amazon ecosystem isn’t uniquely untrustworthy, but it’s not where I want to keep future electronic purchases.
There is a very good open source conversion tool called "Calibre". I use it all the time to convert my, erm, security backups of books I own.
