E-reader suggestion

Hi.

I have an old Amazon Kindle Paperwhite that is showing signs of its age. So I have to start thinking about replacing it.

So I have been really happy with both the Paperwhite and the Kindle store. But I have realised that I should be moving away from Amazon as it's not really a company I would like to keep supporting.

So what are the current best options out there. Mostly reading non fiction books, so no need for colour. But a bookstore with a good selection is critical.

Photo unrelated. But a great read/listen about the dust-bowls in the 1920's.
