We’re not going to engage in too much wild speculation on this piece of information, but there are certainly a few raised eyebrows in Engadget-land right now. Apparently Plastic Logic is no longer offering pre-orders of its QUE proReader, as a tipster of ours discovered while trying to push through his order of the $799.99, 8GB / 3G version of the large-screen device. According to the order page “Pre-orders are sold out. QUE will be available online and in select Barnes & Noble stores this summer.” This of course comes on the heels of news that the company would be further delaying the ship date from mid-April to summer related to “fine-tuning” and “enhancing the overall product experience.” So our minds aren’t exactly at ease, as we’re trying to understand why a company wouldn’t just caveat pre-orders by letting people know there’s been a run on supply — though it’s possible that Plastic Logic is doing separate batches for mail order and in-store, and just needs to pace themselves. We’ve reached out to the company for comment, and we’ll let you know as soon as we hear back

Is it an Android tablet? An e-reader? Just a sweet gadget with two screens? Truth is the Entourage Edge is a little bit of everything, and that’s exactly why we’ve been so intrigued with the “dualbook” since we fondled it at CES .

As specumalated in yesterday’s Giz Explains , Barnes & Noble is coming out with an iPad version of their ebook app, which will, interestingly, include B&N’s bookstore. Really ? More

For all the fuss made at its launch back in August , Sony’s Reader Daily Edition has all but dropped off the map in terms of interest. Remember, Sony’s response to the Kindle gave us a 7-inch touchscreen device with free AT&T 3G data for a street price of $399. Now we’ve got a proper in-depth review of the thing. On the plus side, the interface is simple and easy to understand right out of the box with nice, oversized icons suitable for your meat digit manipulation. Unfortunately, the Daily Reader was also sluggish

The half ereader/half netbook from enTourage eDGe was one of the best gadgets CES threw up in my opinion. While the sale date has been pushed back by a month to March, some more details have been drip-fed to us. In an interview with e-reader-info, enTourage’s President and CEO Asghar Mostafa detailed when the two different displays could be used together: * Drag the stylus across grayscale images on the E-Ink screen to view them in color on the LCD screen * Attach Web pages, notes and video on the WiFi-enabled LCD screen to passages in an e-book * Export PDF notes or revised documents (such as contracts that are marked up on the E-Ink side) so that they can be emailed to colleagues * Open hyperlinks or view video embedded in an e-textbook on the netbook side Tackling the omnipresent iPad issue, Mostafa fingered the larger e-ink screen that “offers a comfortable reading experience,” and because of the LCD screen it makes it “simple to mark-up documents and books with the stylus to save notes or export to colleagues.” At $490 though, it’ll be going head on with the iPad, so enTourage has got a tough ride convincing people to go for a chunky, clunky, plastic device rather than a sleek iPad. During my hands-on at CES I felt it was the build quality which was the only downside to it, but there’s enough features and capabilities tucked within that it should do well. I want it to do welI, anyway—I fell in love with it last month and have the slightly zany device’s best interests at heart. [ e-reader-info ]

Let’s not turn everything with a screen into an ebook reader, pleeeease? The DSi XL is launching in North America on March 28 , and Nintendo’s putting that gorgeous 256×192 display to use with 100 Classic Books June 14. Dear Christ . The 100-book package features works from Shakespeare and Mark Twain and it’s 20 bucks. Mercifully, you can adjust the text size, meaning if you want it to be readable, you’ll be able to scale it up to something like four words per screen.

What’s this we hear? Is it the distant thunder of sanity emanating from Acer’s Taiwanese headquarters? The Taipei Times is reporting this morning Acer chairman Wang Jeng-tang’s announcement that his company will not be releasing an ebook reader “for now.” It was only a month ago that Jeng-tang and his crew were telling the world about the aggressive inroads they were going to make into the Amazon-dominated e-reader market, but it appears some second-guessing has been taking place in those Taipei boardrooms, which has led to the scrapping of the earlier plans. Considering the absolute glut of interchangeable E Ink devices out there, we have to agree with Acer’s perspective; you either have to come up with something unique — like the Nook , the Edge , or the Adam — or just focus your energies elsewhere.

You’ll be forgiven for just glazing over during CES and ignoring all those ebook readers that were raining down , but Liquavista ’s attempt at marrying the endurance of e-paper with the desirability of color is well worth another look . The company has now furnished its LiquavistaColor dev kit with a QWERTY keyboard and also recruited Texas Instruments into the fold, whose OMAP system-on-a-chip is doing the grunt work under the hood. The video after the break indicates that touchscreen interaction is also planned, but the most impressive thing has to be the total lack of any redrawing pauses, which may be the considered the biggest drawback to the many E Ink devices out there. For the more conventional monochromatic crowd, we’ve also grabbed video of the LiquavistaBright, which replicates the rapid refresh skills, but omits the keyboard and OMAP in favor of a more compact form factor and Freescale iMX5x hardware. Slide past the break to see it all

It was threatened , and thus now available. Hit up the BlackBerry App World to download the free Kindle app now—but only if you live in the US. And are happy paying up to a tenner to read a book on a 2.44″ screen. [ THINQ ]

We know that some of you chaps are still waiting for your Barnes & Noble Nook to arrive, but by now, we’re hoping that the vast majority (read: all) of you that were jonesing for one can finally say that yours is in-hand . For those that got one during the madness that is the holiday rush (or yesterday… that works too), we’re interested to know how you’d do things differently. Are you kosher with the dual-screen approach? Is the user interface smooth enough? Would you tweak the e-book buying process?
