Even the thought is hard to believe for anyone who's been watching Apple Inc. (AAPL) over the long run. Once upon a time, the company was presumed dead, while Microsoft Corporation (MSFT) continued its march to market dominance. Today, Apple's $180 billion market value is evidence of a new era. Though it's still behind Microsoft's $250 billion, the company's rapid ascent and substantial market presence make at least speculation of catching up to the Redmond giant worth a few minutes of thought.

Microsoft is currently the most valuable technology company in the world, according to a Reuters report. Even Google, Inc (GOOG), with its astounding brand recognition and position as gateway to the internet, is worth "only" $136 billion. Apple, which was once considered a computer company that sold into education and appealed to some graphics geeks, has reasserted itself as a major global presence.

The Twitter ecosystem may be changing constantly, but most of that comes on the back of individual developers and outside companies. They beat on Twitter APIs to create new products that may win them glory, recognition or cash. Over the past month, though, Twitter itself has gotten into the game, releasing or announcing a handful of new features.

A new function for "retweeting" (echoing another's tweet to your own followers), changes to how trending topics are managed, and the ability to create lists are new tools intended to engage users ... on the Twitter.com website. Considered within the context of Twitter's changed terms of service this year, the upgrades may be part of a broader ad-based revenue plan.

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.

Apple Inc.'s (NASDAQ: AAPL) iPhone has been selling like gangbusters in the U.S. since its debut in June 2007, but that kind of fever -- and the fever U.S. consumers felt at every iPhone launch in the U.S. -- seemed tepid by comparison when China Unicom unleashed the iPhone for sale last week.

Although Microsoft Corp. (NASDAQ: MSFT) has much of the business world wrapped around at least some of its software, the largest software company in the world is mostly known for its consumer products. Names like Windows, Zune, Windows Mobile, Sidekick, and Xbox are household terms (well, in gadget households perhaps).

Still, with all those names, why hasn't Microsoft formed some kind of overall consumer ecosystem so that all these products fit, work, and play together seamlessly?

Google (NASDAQ: GOOG) makes it easier to search for websites, e-mail messages, passages from books and videos. Where you haven't heard much about Google's search capabilities -- or Google in general -- is the music business.

But, that's about to change. On Wednesday, the search giant announced that it was partnering with music services such as Pandora, Lala, News Corp's (NASDAQ: NWS) MySpace, and Rhapsody by RealNetworks (NASDAQ: RNWK) to help users find, listen to and ultimately buy music on the web.

If the Wii were still cool, Nintendo (OTC: NTDOY) wouldn't have had to take a heavy hand to its full-year earnings forecast. The company's profit fell 52% year-over-year for the past quarter, due in large part to a decline in the game's popularity. Demand has slipped, with Sony (NYSE: SNE) and Microsoft (NASDAQ: MSFT) gaining ground with the core market of zealous gamers. Also, it's seen its position eroded by Apple's (NASDAQ: AAPL) iPhone, which is picking up some momentum as a gaming platform.

Nintendo's Q3 operating profit dropped to JPY64 billion ($709 million), falling far short of the analyst estimate of JPY90 billion. For the year ending March 2010, the company has chopped its forecast to JPY370 billion, far lower than the analyst expectation of JPY442.8 billion.

After dominating the gaming industry for the past three years, Nintendo's Wii gave up its position in the top spot to Sony's PlayStation 3 last month. The company has also been hurt by an increase in the value of the yen, which has hurt all Japanese exporters. Yet, even by local standards, Nintendo isn't measuring up. Its stock price is down 28% this year, compared to a 14% increase in the Nikkei 225.

Ever since Apple Computer (NASDAQ: AAPL) introduced the iPhone to the world, other cell phone companies have been working hard to compete. Verizon (NYSE: VZ) is hoping to find success with the Motorola Droid, which will come with a $199 price tag.

The phone will be running on Google's Android operating system, and could be a serious contender against the iPhone, and while most people knew this phone was coming, the real news is that it will start to be sold next week at Verizon's across the nation.

Verizon Communications Inc. (NYSE: VZ) issued Q3 data on Monday. According to the press release, the telecommunications entity made, on an adjusted basis, 60 cents per share. Disappointing, since that's six pennies less than last year's comparable number. However, it was a penny ahead of analyst expectations, according to Reuters.

Of course, when discussing Verizon, what tends to receive focus is cash flow. As we all know, the company is a famous dividend play. Many investors consider this angle to be not only valuable, but an added safety element as well.

The U.S. Chamber of Commerce is fighting back. The organization has filed a civil lawsuit against the Yes Men, an activist group that announced that the chamber had changed its position on climate change.

The Yes Men told the National Press Club on October 19, 2009 that the Chamber of Commerce would give up lobbying against the Senate's 800-page climate change bill. Reuters, CNBC and Fox Business Network all reported on the story, with the anchors correcting themselves midstream, when they learned that it was false.

Nokia Corp. (NYSE: NOK) has been losing market share in the mobile phone business to faster and more innovative companies like Apple Inc. (NASDAQ: AAPL) and Korea's Samsung Electronics. Although Nokia is still the world's largest mobile phone maker by volume, the company's most recent quarterly results don't speak highly of its efforts as of late.

And, when you start suing competitors, your back must be against a pretty hard wall. What is Nokia going to do? Try to innovate again and manufacture wireless handsets that carrier partners are glad to have on shelves and customers seek to purchase? Sorry, the iPhone already has beaten you -- for a few years now -- to the punch. A potential $1 billion judgment against Apple is proof in the pudding. But if Nokia thinks some of its newer phones can compete with Apple as easy as other competitors, Nokia is dead wrong.

Barnes & Noble Inc. (NYSE: BKS) recently announced an electronic e-reader to compete with the likes of the Amazon.com's (NASDAQ: AMZN) Kindle and Sony Corp.'s (NYSE: SNE) Reader.

In perfect holiday fashion, the e-reader is set to become the "must have" gadget for the gift-giving season almost upon us. The newer Nook device has a small color screen that allows easier content locating (but no keyboard), the ability to "lend" digital books to a friend and built-in wireless internet.
