Amazon, Inc. (AMZN) is in the clouds. So are Google, Inc. (GOOG), EMC (EMC) and Cisco (CSCO). Now, Microsoft Corporation (MSFT) is joining them, having announced on Tuesday its new Windows Azure cloud computing system. The new product will be released on January 1, 2010 -- a new solution for a new year.

Azure will deliver an online platform for the software development set to build their own mousetraps and provide plenty of storage space for users. Testing began a year ago, and full live version will be celebrated next year. For the first month, Azure will be free. The charges start in February.

Okay, so we all know retailers are looking for every holiday edge this holiday season. Consumer spending's been down, and the sprint to Christmas offers the last chance to pump up those Q4 numbers. They are trying out new ways to reach and engage shoppers, particularly via social media. But, the most effective way to bring new customers into the fold -- and keep them around for a while -- may be to pick up the shipping tab. It's pretty old fashioned, but it's best by test.

Once considered a bonus, a special effort, free shipping isn't really optional any more. If a shopper has to pay for shipping from one retailer, he may move on, knowing that plenty of others aren't charging for it. Rebecca Lieb, vice president at Econsultancy, a digital marketing news publisher, notes, "You're delighted the first time you get free shipping, but you expect it the second time."

And, free shipping shouldn't come with any strings attached, according to Shop.org's eHoliday Study (Shop.org is the e-commerce division of the National Retail Federation). Five years ago, 25% of retailers didn't charge for shipping during the busiest shopping day of the year. This year, however, 57% are planning not to hit their customers up for the extra cash, making this cost just another expense associated with running the business during the holiday season.

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."

Santa hasn't even been tugged down Central Park West yet, and Wal-Mart (WMT) is already slashing its prices. The market among major retailers is intensifying, with many offering products as loss leaders in order to entice customers into the store (physical or otherwise) and boost their basket sizes. Along with Target (TGT) and Amazon (AMZN), Walmart is slashing DVD prices, the same tactic it's using with books.

Retailers are rushing to undercut each other this year, which is causing prices to spiral down quickly. When Walmart announced reduced prices on several titles to $10, Amazon followed at $9.99, with Walmart stepping back in at $9.98.

While eBay (NASDAQ: EBAY) has been working hard to manage its marketplace in a trying economy, its PayPayl business has been growing comfortably and could become the company's biggest earner. For the past two years, eBay has focused on improving the look of its website and helping buyers and sellers to get along in a virtual world built entirely on trust.

In the background, though, the segment of the business that moves money from Point A to Point B has been on fire. Even with payment processing competition from Amazon (NASDAQ: AMZN) and Google (NASDAQ: GOOG), PayPal has been able to do more than hold its own.

Best Buy (NYSE: BBY) may be the world's largest electronics retailer, but it realizes that it faces a huge threat to a hefty chunk of its business. Apple (NASDAQ: AAPL) is moving plenty of movies and other soon-to-be former DVD fare through iTunes, staking a claim on a business that once belonged to Best Buy. The big box store is getting ready to fight back (finally?).

Using technology it's licensing from Sonic Solutions (NASDAQ: SNIC), Best Buy is opening an online store for movies and television shows. Best Buy CEO Brian Dunn says this move will expand the company's presence in services and will bolster company loyalty. That's the press release version, of course. The reality is that Best Buy needed to do something to protect this portion of its revenue and probably should have made the move several years ago.

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%.

Small book retailers were buying in bulk from major online booksellers because they could really save some money. One was buying up to 70 copies of a particular title -- it was $5 less a pop from the big guys than it would have been from the publisher. Finally, however, the big retailers have become wise to the trend and taken action, according to the Wall Street Journal (subscription required).

Wal-Mart (NYSE: WMT), Amazon (NASDAQ: AMZN), and Target (NYSE: TGT) have decided to cap the number of books customers can buy online, a measure intended to prevent smaller competitors from treating them as partners. Walmart is limiting customers to two copies of a particular book, with Amazon placing the border at three and Target at five.

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.

Online auction giant eBay (NASDAQ: EBAY), a business that counts Amazon (NASDAQ: AMZN) and Yahoo! (NASDAQ: YHOO) as related companies, was not popular in Wednesday's after-hours session. The third-quarter report just didn't do it for Wall Street, so Wall Street decided to make some trouble and bring the per-share price of the stock down by 4.5%. Oh sure, the company beat earnings by the most famous amount there is -- the proverbial penny -- but, according to this Bloomberg piece, guidance was not so inspiring.

The top line was actually pretty cool. Net sales saw an increase of 6%. Unfortunately, the bottom line couldn't take advantage of such growth. On an adjusted basis, net income dropped 16% to 38 cents per diluted share. And, as I just said, that was one penny ahead of the analysts.

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.

As you walk by the corner of East 59th Street and Fifth Avenue, it's hard to miss Manhattan's temple to retail tech. The Apple (NASDAQ: AAPL) store stands out amid the older, more traditional stores in the area -- both for its giant glass cube and what happens when you descend into it. So, is it so hard to believe that Microsoft's (NASDAQ: MSFT) move into the space could be successful?

At the turn of the century, the notion of Apple stores was mocked, with BusinessWeek proclaiming in May 2001, "Sorry, Steve: Here's Why Apple Stores Won't Work." Of course, it turns out BusinessWeek is what doesn't work, as evidenced by its recent acquisition by Bloomberg.

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.
