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.

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.

One would think that Google Inc. (NASDAQ: GOOG) and Apple Inc. (NASDAQ: AAPL) would be friends. Google CEO Eric Schmidt sits on Apple's board and his company partners heavily with Apple's iPhone for Google's web products. That is, except when Google is trying to do an end-run around Apple partner AT&T Inc. (NYSE: T).

This is what it comes down to: Google Voice, the service that gives you a universal phone number that you have total control over (and even provides free text messaging!) was blocked by Apple's App Store, most likely at AT&T's request. After all, AT&T surely does not want customers bypassing its margin-heavy text messaging plans to use a free Google-provided solution.

Apple, Inc. (NASDAQ: AAPL) and Palm, Inc. (NASDAQ: PALM) just keep volleying with each other with the duel between the iPhone and the Palm Pre, don't they? Accusations of an
"iPhone copycat" surfaced right after the Palm Pre was announced. After all, quite a bit of Apple design influence now works at Palm. But the war is not over yet, as one of the neater features of the Palm Pre has now been deactivated by Apple.

"China Unicom (NYSE: CHU) could be one of the best ways to play China's astounding economic growth," says Brandon Clay in Invest with an Edge. Here's the growth advisor's review.

"With the world's largest population as its market, the mobile phone industry in China is set to soar. This makes China Unicom a compelling play. The firm has 21% market share in China.

"China Unicom's vice president recently said the company is targeting subscriber growth of 20 million to 30 million within a year. To put that into context, Verizon Wireless, the largest mobile phone carrier in the U.S., had 72.1 million subscribers at the end of last year.
