Haven’t got your Nook yet? You may actually be in luck. For people who pre-ordered early enough to expect a pre-Christmas delivery, Barnes & Noble is promising a $100 B&N.com gift card if it misses December 24th — which is apparently distinctly possible. Of course, if you’re one of the lucky / unlucky ones to have this on offer, you’ve probably already seen the email, and if you’re a different sort of hapless pre-orderer that won’t be seeing a Nook until next year, this is just another reason to curse your lot in life. To think: not only are you not ushering in 2010 from an economy suite in a space hotel, but you’re going to wrap up this year reading paper books, without $100 to show for it! Can’t we do better as a civilization?
