Trying to get away from Amazon. ALL my ebooks from them I have DRM removed & put them in epub format. When I started this I also had a Litterati..which was epub. Now have over 1500+ don't want to reload & change format

call me lazy
OK except for Litterti & Nooks I no clue which of the millions of e-ink readers use the epub format AND that I can walk into a B&M store & buy in the USA.
No Nooks! Had 2 both were broke out of the box.
Not buying used! Want new!
