A new business model is springing up right under our noses. The big players like Apple (AAPL), Amazon.com (AMZN) and Google (GOOG) have put together a one-stop shop in their app stores.

First off, an app store is just that, a place where you can pick and choose the apps you want to download. The app store is also a place where entrepreneurs can develop an app and with permission place it on the iPhone, iPad or Android device.

The fast moving world of investing can turn on a dime, especially if you own technology stocks. Research In Motion (RIMM) was a smartphone darling. But then came the iPhone and now the iPad. Then we have Google's (GOOG) Android following on Apple's (AAPL) heels.

RIM suddenly woke up a found that it had fallen off its perch. Now the company is scrambling to do catch up. BlackBerry is losing North American market share and the company expects to ship only 13.5 to 14.5 million Blackberry's this quarter, down from 14.9 million last quarter, according to Reuters.

Research In Motion (RIMM), which designs and develops the BlackBerry line of smartphones, is also expected to launch its PlayBook tablet in the first quarter of 2011. RIM, which competes with Apple (AAPL), Motorola Mobility (MMI) and Nokia (NOK) in the mobile phone market, is expected to face stiff competition from Apple's iPad and Google's (GOOG) Android-based tablets.

RIM lacks the apps ecosystem strength enjoyed by Apple and Google, one reason why RIM has been slowly losing its share in the smartphone market. Without a conscious effort to improve its app platform, RIM's PlayBook may not gain much traction in the tablet market.

Google's (GOOG) mobile operating system, Android, is an example of how acquisitions have made a big difference. This technology came from a deal struck in 2005. Then, after lots of internal development, Google launched Android in 2007. Since then, the growth has been sizzling.

In fact, according to the most recent report from comScore, Android's market share hit 31.2%. Yes, it is now the number one mobile operating system.

Google's (GOOG) Android smart phone operating system has seen tremendous adoption over the past year as its market share has increased from a mere 6% in 2009 to around 24% by 2010. This has come at the expense of smart phone operating systems from Nokia (NOK), Research in Motion (RIMM) and Microsoft (MSFT). The other main competitor, Apple's (AAPL) iPhone OS, saw a slight increase during this time period from 26% to 28%.

We believe that Android's success has to do with the fact that it partnered with smart phone makers like Motorola Mobility (MMI), Dell (DELL), LG and Sony Ericsson (SNE) in providing its OS. Higher Android adoption helps Google by enabling more mobile searches from Google's platform as Google is the default search engine on Android phones.

Lately, Research In Motion (RIMM) has been ramping up its dealmaking. Some of the recent transactions include QNX, Dash Navigation and Torch Mobile.

Tthe latest deal came this week: RIM agreed to buy Gist (the price tag was not disclosed). The company develops a service that prioritizes incoming messages. It even provides the user with helpful research information on contacts, such as from social networks and blogs. The app is currently for Apple's (AAPL) iPhone and Google's (GOOG) Android devices.

Apple, Inc.'s (AAPL) gibe at Google Inc.'s (GOOG) Android OS is that it was not designed for tablets. Google answered that challenge last week with the launch of Honeycomb. Motorola Mobility's (MMI) Xoom, due out later this month, will feature Honeycomb and should make a splash in the tablet market as competition heats up among tablet manufacturers and affiliated operating systems.

Even with the older version, Android has already started to dent iPad's market share due to the success of Samsung's Galaxy Tab, and we expect that Xoom could improve Android's position intensifying the showdown between Android and Apple's iPad OS.

First we had the iPhone revolution. Now, The Financial Times reports that Apple (AAPL) is planning to expand the iPhone to handle mobile commerce, giving the company access to the multibillion-dollar transaction industry.

You are probably wondering what and how this will be done. The iPhone 5, due out this year, likely will incorporate technology called Near Field Communication (NFC). NFC incorporates financial account information and ties the data to specific devices.

As everyone knows by now, the Apple (AAPL) iPhone is headed for Verizon's (VZ) reportedly more reliable network. With so much excitement over the announcement, traders and investors can look at various ways to profit off of this.

The obvious beneficiary is Apple, but there are additional ways to play it, such as the advertising companies, as Verizon hits the airwaves to promote the iPhone, even at the expense of the Android. A few ideas to consider include names like CBS (CBS) and Viacom (VIA), which should win no matter which platform wins.

The battle among iPhone carriers is fierce. Apple's (AAPL) iPhone is the prized device. AT&T (T), Verizon's (VZ) rival, has had the an exclusive hold on the iPhone. Verizon has been trying to play catch up. Now that Verizon will have the iPhone, the playing field will change dramatically. Verizon, with about 93 million subscribers, could grab an estimated 10 million new subscribers with the iPhone, as reported by the Wall Street Journal.

The move is also a big boost for Apple. Apple has been feeling the pressure from Google (GOOG), with its Android system. Android phones passed the iPhone in sales in the second quarter. This move to Verizon will open up a new expanded base for Apple.

As the e-commerce boom continues, the shares of Amazon.com (AMZN) have been hitting new highs. The company now sports a market cap of a hefty $83 billion.

Besides strong customer service -- and tremendous efficiency -- Amazon.com has also been adept at consolidating markets. It's a big help to consumers.

The wireless communication world is about to receive a new entrant, as the country's third-largest cable company will start a cellular network in three areas today. The company? Cox Communications.

Before you think that this wireless network will be available across the U.S., Cox's wireless offerings will be available in Orange County, California; Omaha, Nebraska; and Hampton Roads, Virginia. These three locales are where Cox is the local cable company, and they hold roughly 1.5 million residents.
