I just put several epub books on my brand new Nook STR via calibre. Ran out of space. Not sure how many I added -- probably 100. Initially (and so far) the Nook would not connect to my home wifi network (kept saying on it that my password was wrong -- but it was right). So I can't register it but also cannot access homepage or library, settings or anything else except the access wifi pages.
Very disappointed so far. I always liked the Nook STR when I played with the demo models.
