Just a heads-up to Kindle users:

If you sideload books onto it via usb or email, like when you put your collection of "free" .azw3 ebooks on it, don't let your Kindle connect to the internet. Keep it in airplane mode always.

Why? Because if it connects it'll simply delete all your sideloaded books.

I assume it's some kind of assholish anti-piracy measure. "Use the eReader you paid a lot of money for exclusively for buying books from Amazon, don't use it the way you want, or we'll gently caress you over".
