I bought a kindle when amazon sold them for a special price of 25 Euro. It’s a cool device for reading books, but I found their UI horrendously cluttered and filled with “suggestions” instead of focusing on the content I already have. I have since jailbroken the device and am using koreader on the device to read my ebooks transfered as epubs via calibre.

That has the advantage that when I buy DRM-free books in epub format, I am not relying on amazon to properly convert the file to a kindle proprietary format.
