Research In Motion (RIMM) recently announced the fiscal year Q4 2011 earnings, in which it gave a disappointing revenue outlook for FY Q1 2012 quarter. Its shares tumbled by 10% in the after-market hours after the announcement and opened around these levels Friday morning. RIM, which competes with Apple (AAPL), Nokia (NOK) and Motorola Mobility (MMI) in the smartphone market, stands to lose further ground in the near-term as suggested by the weak outlook. However, we still believe there is value for long term holders of the stock despite the disappointing guidance.

We have updated our price estimate for RIM stock to $69.59, which is about 25% higher than market price.

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.

A few weeks back, we noted that while Apple's (AAPL) products continue to see huge demand, a key concern for the company is management of supply-related constraints. The recent Japanese earthquake has now added to these concerns. According to market research firm iSuppli, the earthquake may cause logistical disruptions and supply shortages for the newly launched iPad 2. Although Apple remains king of the tablet market, it is expected to face a growing set of challengers in 2011 from Research In Motion (RIMM), Motorola Mobility (MMI), Dell (DELL), Samsung and LG.

We maintain a $420 price estimate for Apple stock, roughly 25% above market price.

The shares of Research In Motion (RIMM), which I first wrote about on May 5, 2009, at a price of $77.07, remain a stock that's decidedly not for the squeamish.
RIM's roller-coaster rebound continued during the winter, with the stock rising from $61 to test $70 resistance, before retreating back to $62.

RIM's 2011 revenue will likely jump 35% to 40% on strong sales of BlackBerry wireless email devices -- a device that has become the standard in large corporations and public institutions, and that is gaining traction in the consumer segment. Unit sales and subscriber growth remain adequate, but average selling prices are likely to continue trend lower amid increased competition. Revenue from tablets also should begin to make their presence felt in 2011. In 2010, Research's revenue surged 35%.

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.

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.

It's not enough to be on every metropolitan street corner; now Starbucks (SBUX) is trying to be even bigger (in one sense of the word) -- and faster, too. Thirsty folks longing for a Big Gulp­-style coffee beverage are in luck as the Seattle-based coffee chain is set to roll out its new "Trenta" size for iced drinks.

The new size, seven ounces bigger than the Venti, will be 31 ounces. Trenta, by the way, means "thirty" in Italian. It's also a valley in Slovenia and a small town in the Italian province of Cosenza. This new size trumps Dunkin Donuts, which offers its iced beverages in 24-ounce serving sizes.

The BlackBerry is still the device of choice among corporate users, according to Research In Motion's recent third-quarter earnings report. The Canadian smart phone maker (RIMM) announced a 40% growth in shipments from a year ago to 14.2 million units.
