Figures. Just yesterday we write about all the different e-books you can get your hands on this holiday shopping season, and then we get a bombshell:Barnes & Noble is 100 percent sold out of nook. The company says that it has exhausted its current supply, and will only have enough nooks to fulfill current pre-orders. In other words, if you were thinking about getting a nook for Christmas (or whatever holiday you celebrate) but didn’t pre-order one yet, well, too late now.

It’s not fun being the coolest kid in town as Barnes & Noble just found out. Its hot dual-screen Nook ebook reader was supposed to ship on November 30th, but that’s not going to happen. Sorry. The good news is that buyers should still get it before Christmas though.

Books, books, books! The American Booksellers Association, a trade group that represents small bookstores (not Barnes and Noble and the other big guys), has asked the Department of Justice to investigate whether or not Amazon, Wal-Mart, and Target have “[devalued] the very concept of the book” with their ongoing price war. Well, they’re actually asking for an investigation into their selling practices. That is, because Amazon wants to outsell Wal-Mart, and Wal-Mart wants to outsell Amazon, they both sell the latest book (think Stephen King, Dan Brown, etc.) for some really low price, like $10. When you consider that the average hardcover “should” cost something like $20-$30, just based on the wildly outdated economics of book-selling, then you understand why the ABA is so upset.

The Nook, Barnes & Noble’s new ereader, has upped the ante. With a small, 3.5-inch LCD screen in the lower quadrant, the Nook adds touch capabilities that the Kindle definitely does not have.

So who will win the ereader race? While no one in particular has to “win” the race, it’s abundantly clear that Amazon has a head start. B&N was late with their readers, starting with a Kindle-like IREX and ending up with an odd duck that uses e-ink for text display but also adds a bit of UI richness with the color LCD. The specs promise an interesting experience and it’s especially nice to hear that the device will last for 10 days with wireless off, a bit longer than any of the Kindle family.

That’s no fun. Barnes & Noble was probably expecting to get all the attention tomorrow with its fancy-pants press conference, but the Wall Street Journal had to go ruin all the fun by letting the Nook ebook reader out of the bag today. Yeah, that’s the name. Nook.
