If Amazon (AMZN) was comfortable with its spot atop the e-reader market, it just got a wakeup call from Barnes & Noble (BKS). The brick-and-mortar book retailer's e-reader, the Nook, which hasn't even hit stores yet, is in pre-order nirvana right now. The first run for the Nook occurred at the end of October (the product was introduced on October 20). These buyers were told the reader would ship on November 30. High demand resulted in backorders, so the next wave of pre-orders was scheduled to ship on December 7. Now, a third group will have to wait until December 11.

This product is on fire, and it still isn't even on shelves yet.

Mary Ellen Keating, a spokeswoman for Barnes & Noble wouldn't reveal how many of these devices have been pre-ordered, but she did say, "Demand for the product in our stores and online has surpassed our expectations." She also noted, "We are working hard to meet demand for the holidays."

Two of the newsletter industry's leading growth stock advisors remain bullish on the prospects of online retailer Amazon.com (NASDAQ: AMZN), based on growth in not only online retailing but new market areas ranging from the Kindle e-reader to cloud computing.

Mike Cintolo, editor of The Cabot Top Ten Report, explains, "Amazon.com recently blew away earnings expectations." Meanwhile, Alexander Green, investment director at The Oxford Club, says, "In our view, the best lies ahead for the company." Here are their reviews.

Mike Cintolo continues, "Amazon announced that its Kindle e-book reader is now its most popular selling item, both in units and in dollars. That led to a big acceleration in revenue growth (28%, the fastest in five quarters), while earnings leaped 67%.

Amazon (NASDAQ: AMZN), simply put, had a quarter to die for, the kind that all shareholders have on their wish lists. The Q3 numbers, which were released on Thursday after the bell, speak for themselves. Net sales: up 28%. Operating income: up 62%. Per-share profit: up 67% to 45 cents. Free cash flow for the trailing twelve months: up 98%. Yep, Amazon's fundamentals seem to be heading in the right direction.

According to our earnings preview, Wall Street was on record as wanting to see 33 cents per share on the bottom line. Amazon's management did a fine job of supplying further evidence to the market that the company's online business model is not only here to stay, but that it should provide shareholders with a significant amount of value over time.

As expected, Barnes & Noble (NYSE: BKS) has announced its entry into the e-reader market. The top bookseller, with green stores all over the country (and, for that matter, my neighborhood) is eager to get a taste of of the success Amazon (NASDAQ: AMZN) has realized with the Kindle.

The Barnes & Noble e-reader, which will be called the Nook, will be available at the company's more than 750 locations in the United States at a price of $259. Essentially, it's coming in at the same spot as the Kindle, which currently owns 60% of the U.S. market.

For retailers, the crucial season is on its way. Blow the Christmas rush, and next year starts off on a miserable foot. Success, of course, also delivers a healthy dose of momentum -- and a little bit of wiggle room, important in what will continue to be a tough economy through at least the first half of next year. For booksellers, now contending with a new variable in the form of digital readers, e-readers will play a major role in defining the winners and losers. So far, it looks like Amazon (NASDAQ: AMZN) is off to a great start, and it will take some genuine innovation for the competition to chip away at its market share.

Barnes & Noble (NYSE: BKS), once the leading names in literary retail, is expected to release its own e-reader this week. It will look a bit like Amazon's Kindle, according to Reuters, but with a touch screen intended to make the reader's experience easier. The price hasn't been disclosed yet, but rumor has it that it'll be higher than the Kindle's $259. BKS is staying mum on its plans in this space. There are others in the space, as well, including IREX Technologies, which is a spinoff of Royal Philips Electronics (NYSE: PHG), Asutek (tk: tk) and a project called FirstPaper that has Hearst behind it.

Digital technologies have wreaked havoc on media like newspapers and music. Might books be next?

Well, Amazon.com's (NASDAQ: AMZN) Kindle has shown that people are willing to curl up with a device when reading a book. But how big is this market really?

It's too early to tell. But this isn't stopping the competition. On Thursday, Google (NASDAQ: GOOG) said it will launch its own digital book selling service. It's called Google Editions and is expected to hit the market in the first half of next year (in the U.S. and Europe).

With the Apple (NASDAQ: AAPL) Tablet, newspapers doing what they should have done: thinking about the possible impact to their business and trying to find ways to mitigate it. This comes 15 years after the industry ignored the internet and a decade after it disregarded Google (NASDAQ: GOOG). Of course, unwilling to admit its salient and severe fallibility, the newspaper folks are saying that they don't want the Tablet to destroy print the way the iPod destroyed the music industry.

The newspapers are apparently worried that circulation could plunge, driving profits through the floor and jeopardizing their abilities to operate. They are concerned that properties like the New York Times Co.'s (NYSE: NYT) Boston Globe could wind up selling for a single-digit percentage of the original purchase price.

In the past, it has been the Nintendo (OTC: NTDOY) Wii or Apple's (NASDAQ: AAPL) iPhone creating holiday hype -- what product will it be this year?

Quite honestly, none. The tech realm is still looking for the next big holiday hit. This is why it appears that we could be facing a holiday season full of buy-one-get-one-free specials or pushy salespeople trying to get you to allow their company to install the new flat-panel TV or add ons that will help integrate your home entertainment system.

So, what does this mean for electronics retailers?

By 2013, more than $4 billion will be spent on smartphone applications, according to a new study by the Yankee Group ... and the estimate is said to be conservative. With the average owner of one of these devices downloading around 20 applications a year, it's obvious that this market is getting ready to pop. Currently, only $343 million is spent in this space.

An increase in the number of smartphone applications available -- for Apple's (NASDAQ: AAPL) iPhone, Reasearch in Motion's (NASDAQ: RIMM) Blackberry, and Google's (NASDAQ: GOOG) Android -- and rising prices for these applications will push the total size of this market higher.

We've all heard of Amazon.com's (NASDAQ: AMZN) Kindle -- perhaps you've even seen it in the flesh. It's portable, well-lit, and comes equipped with wireless technology so a user can download a new novel on the fly.

The competing device, Sony Corp.'s (NYSE: SNE) e-reader ... well, it's portable and well-lit. But if you run out of reading material and you're away from home, too bad. Until now.

Rumors continue to swirl that Sony is not far off from unveiling a wireless version of its Reader. The company's e-reader group has extended an invitation to reporters for a meeting on August 25. Could a wireless announcement be in the offing?

A report today in The Wall Street Journal (subscription required) reveals that Sony Corp. (NYSE: SNE) is set to launch two low-priced e-readers, which could prove to be stiff competition for the wildly popular Kindle devices sold by Amazon.com (NASDAQ: AMZN). Sony's latest entries in the e-reader market, known as the PRS-300 and PRS-600, will be priced at $199 and $299, respectively. By contrast, the cheapest Kindle will run you $299.

Sony's budget-friendlier devices are slated to hit store shelves later this month, with the Journal citing Best Buy (NYSE: BBY) and Wal-Mart Stores (NYSE: WMT) as two retailers planning to offer the e-readers. Meanwhile, the low pricing isn't limited to the gadgets themselves; Sony will also drop the cost of best-selling titles from $11.99 to $9.99, matching the deal offered by Amazon.

Online retailer Amazon.com, Inc. (NASDAQ: AMZN) is looking to extend the reach of its Kindle -- a wireless reading device -- into the hands of consumers, and hopes that cutting the price will speed adoption in a price-sensitive world. Formerly priced at $359, the Kindle will now be sold for $299, though the more advanced Kindle DX will still maintain its $489 price tag.

Amazon, known mainly for selling books online before branching out into other areas, has made the Kindle a focal point of creating new growth for the site. The company has been offering generous 10% payouts via its affiliate program for creating sales, compared to the typical 4% paid on other items. A June 30 research report from Cowen & Co. obtained by DailyFinance estimated that 800,000 Kindle units had been sold so far; the company estimates that more than 2.6 million will be sold by the end of 2010.

The next all-American brand is the world's largest bookstore, Amazon (NASDAQ: AMZN). Actually, it's not quite correct to call Amazon just a bookstore anymore.

Relentless expansion has propelled Amazon in countless directions in the quest of bigger sales and profits. The company's main website now offers everything from books to auto parts to groceries!

Shoppers can also download digital content, such as games, MP3s, and movies to their computers or handheld devices -- including Amazon's innovative portable reader, the Kindle, which is on fire.

There's been some news on the Amazon (NASDAQ: AMZN) Kindle, the company's electronic substitute for real paper books. According to this source, everything is coming along fine for the product from a statistical point of view. An estimate of Kindle sales from Citigroup Global Markets puts the number of units sold last year at 500,000. By 2010, it's said that the Kindle may lead to $1.2 billion of derivative sales. I was surprised to learn that this sales number would possibly represent 4% of Amazon's top line.
