Either the Nook is set to become more popular than the Kindle or Barnes & Noble is having very serious trouble with manufacturing the device. This morning the bookseller changed the next ship date available for its ereader to January 15th, up from January 11th.

For those of you who have already pre-ordered, it’s no big deal. Existing ship dates should not be effected. Anything from here forward, though, will be subject to the new date. It’s not terribly unsettling news, but it does make you wonder just what sort of further delays to expect. People are already waiting on pre-orders that were placed shortly after the device was announced.

By far the worst part, if you were hoping to catch a Nook in stores, is that no in-store purchases will be available. Barnes & Noble has committed itself to fulfilling the pre-orders that have already been placed. How very…noble.
