The advantage of the nook over a kindle is simplicity when you aren't buying a book (ie, when you're obtaining a digital backup of a physical book you own, library digital checkouts, or you're pirating one.)  All the books I buy are from Amazon, and so with the nook it won't sync those which is unfortunate.  But where it shines is when I refuse to buy a book because the publishers are being greedy (eg, Dance with Dragons by George RR Martin, game of thrones series...  The ebook costs more than a physical copy.  It even costs more than a physical copy translated into another language!  Give me a break!)  So anyway, when it comes down to piracy to keep the publishers in check - the nook is great.  You plug it into USB, it shows up as a drive on the computer.  You type in the name of a book into google and add "epub download" to the end, and somewhere on the first page of results is a working download (at least with every book I've had to try so far.)  Download that straight to the nook's drive letter and you're done.
