I would take one if i also could use it as replacement for my kindle.

If you are willing to strip the DRM and convert the files to epub or PDF, you can read them on the Remarkable 2. I do this as I prefer to read on the Remarkable 2 (compared to reading on the Kindle). It's just convenient to have all the technical material, notes and the leisure reading in one place.

I do this too. As well as ebooks, I have all my household manuals on it (washing machine, gas boiler, etc.) plus manuals for various devices - so much better than either keeping the paper ones, or keeping PDFs on the computer, as you can annotate them too!

If it runs android, you can use the kindle app.

You might be thinking of the Boox Note line of devices. The Remarkable runs a custom Linux distro, not Android.
