Usually battery estimates are longer than reality, not shorter (unfortunately). That said, the nook is the only major ebook reader on the market with a user-replaceable battery. If I were in a position where I would have to go weeks without a power outlet, I'd just buy a few batteries and charge them up before leaving. Can't do that with a Kindle or a Sony Reader.
