If you want to get a Nook for this holiday season, you better get on that right away. The Nook is proving so in demand that they are pushing the second wave of pre-orders into the first week of December.

Many customers are delaying their order until they see the e-book reader in person at Barnes & Noble. Apparently display units should start arriving at the end of November, but it looks unlikely that there will be any units to sell. That means that you may have to get it sight unseen if you want delivery before the holidays. The cost is $260.

Looks like we have some early images of Barnes and Noble’s e-book reader. As we covered before, this thing is supposedly set for a Spring 2010 release, with a color display.

Then there was word that it would not have a color screen. But it looks like there is truth to both of those rumors. Apparently the dual-panel device will feature a typical e-ink display on top with a multitouch panel underneath. Think of it as a Kindle/iPhone mashup.

Your choice of e-reader devices continues to grow rapidly. And now LG is showing off its Solar Cell e-Book reader. The prototype has an energy conversion efficiency of about 9.6 percent. That means that it gives you an extra day’s worth of power to continue reading on that 6-inch TFT-LCD after four to five hours in the sun.

LG is working on getting that solar cell energy conversion efficiency rate to 12% by 2010 or up to 14% by 2012. Great news for bookworms, not so great if you have to read for your homework.

We now have some images and specs on a couple of new Sony e-book readers, the PRS-300 and PRS-600. The PRS-300 has a 5″ LCD display without audio output, and it will also lack a memory card slot. But you do have 440MB of storage space.

The PRS-600 is the better model, equipped with a 6″ touchscreen display along with audio output and an SD/MS memory card slot. You also get 380MB of storage space. We don’t know if they have Wi-Fi yet, which is what we really want to know.

Here’s an e-book reader that does things that the Kindle 2 won’t. Like fit in your pocket and have built in PDF support. The reader weighs in at just 5.3 ounces and packs a nice resolution of 200 DPI. Some other features include a 6″ display, 1GB of flash memory that can accommodate ePub, PDF, HTML and text formats. You’ll also have access to a catalog of 150,000 books.

Software features would let users pick one of 12 font sizes for readability as well as let owners organize e-books by folders. Battery life will give you about 8,000 page flips, which is quite a few novels(Or one Robert Jordan Wheel Of Time novel.) No 3G wireless feature, but you’ll get 21 days at standby.

Here’s yet another E-Book contender. Much Cool-er than the Kindle if it’s name and fancy color is any indication. The Cool-er is by Neil Jones, an avid reader and entrepreneur. It boasts a larger selection of titles and will target an early June release date.

How many titles? It comes complete with 260,000 paid-for titles at launch from all the major publishers. 60,000 of those will be available in the UK and Europe initially. You also get a choice of eight different colors and languages for the Coo-ler.

Typically, translating any book into braille more than doubles its thickness. But with e-books that doesn’t have to happen. Designer Seon-Keun Park, Byung-Min Woo, Sun-Hye Woo and Jin-Sun Park want more blind people to be able to enjoy books, so they created this Braille e-book concept.

The idea is that this is a braille Kindle. Using EAP technology, it can change the surface pattern via an electromagnetic signal that will simulate braille text. It’s an elegant and simple solution that would enrich the lives of blind readers quite a bit.

Peer pressure. It affects companies too. And since everyone else is getting in on the e-book reader craze, why not Barnes & Noble too? That’s the rumor anyway. Why wouldn’t they want a slice of that action? Some “insiders” have supposedly been talking about the possibility.

Just like the Kindle, it would supposedly be connected to a cellular carrier for some connectivity. According to one mysterious someone, Barnes & Noble had been in talks with Verizon, but that didn’t pan out. Now it would seem that Sprint is a possibility. Some aren’t ruling out AT&T.

Fujitsu has finally released its color e-book. The device features an 8-inch XGA screen capable of displaying 260,000 colors, along with Bluetooth, WiFi and up to 4GB of storage via SD card. It measures less than half an inch thick.

Color isn’t the only thing. Fujitsu is promising 40 hours of continuous use. The unit can be operated by its touchscreen or the function buttons. The Japanese version of the device even includes Windows CE 5.0. FLEPia ships on April 20th in Japan for about $1,010.

Boy Genius has some pics of what is in all likelihood the Kindle 2. You’ll notice that this follow-up to the original reader is more rounded, more iPod-esqe, but still in boring white with the same screen. The LCD status bar is nowhere to be seen and a joystick replaces the clickwheel, and so you can avoid accidental page turns, it sports smaller buttons. The SD slot is gone too, since there’s 1.5 gigs on-board, along with grills on back that may mean stereo speakers.

Basically, it’s a lot less ugly. Current Kindle owners can probably skip the upgrade unless the ugliness of the original is really bugging you. No word on the availability yet. Hit the link for more pictures.
