The market for single cup roasters is estimated at $4 billion, according to Reuters. Single cup coffee roasters are growing in popularity, especially in business offices and waiting rooms. Naturally, coffee roasters like Green Mountain Coffee (GMCR) and Starbucks (SBUX) want a piece of the action.

The single cup roasters provide several advantages to having coffee in larger coffee pots. For one thing, coffee which sits for hours in a pot loses some of its fresh flavor or becomes bitter. Enter the single cup roaster. You simply pop a small container of coffee in the machine, and viola, you get a single cup of coffee with little or no mess, and always fresh.

The recession took a nasty toll on NetJets, one of Warren Buffett's holdings. While the company made a profit of $207 million in 2010, it lost $711 million the year before, Bloomberg reported.

NetJets owns a fleet of business aircraft and lets customers buy hours of flight time. With the economy picking up steam, Buffet apparently feels that demand for his aircrafts will also grow.

Economist Gary Shilling has agreed to share with BloggingStocks his 18 investment strategies for 2011, beginning with Gary Shilling's Investment Strategies for 2011. But he will only be revealing them a little at a time, over the next few weeks, so check back often!

My investment strategies for 2011 are driven by my forecasts for the economies and financial markets here and abroad. In my view, the overarching reality that will dominate 2011 and, indeed, the next decade or so is financial deleveraging, as spelled out in my new book, The Age of Deleveraging: Investment Strategies for a Decade of Slow Growth and Deflation, which was published in November 2010 by John Wiley & Sons.

Yesterday marked a pretty big day for Verizon Communications Inc. (VZ), as customers could finally walk into a Verizon store and pick up an iPhone. Some analysts had expected to see some long lines, but they did not materialize, creating the impression that the launch was less than successful, but looks can be deceiving.

It is easy to understand where the confusion comes from. In the past, whenever Apple released a new iPhone we saw long lines and often not even supply to cover the launch date demand, resulting in long waits for eager iPhone fanatics to get their hands on the new smartphone.

Tomorrow is a big day for Verizon (VZ) customers who have been waiting to get their chance to join the iPhone revolution, and we now learn that Wal-Mart Stores (WMT) will also be carrying the Verizon iPhone 4 at 600 retail stores across the nation.

As of today, when you visit Apple's (AAPL) website you are given the option to order an iPhone for use on either AT&T (T) or Verizon, with the price being the same for either option.

There's a new industry in the making. It's in the way we buy and read books. Electronic books, or e-books, are taking the book market by storm. Here's a mind blowing statistic. Barnes & Noble (BKS) announced that in December its e-book sales exceeded print books, as reported in MSNMoney.

The two big leaders in the e-book market are Amazon.com (AMZN) and Barnes & Noble with the Kindle and Nook readers respectively. Both companies said that e-readers are their best-selling product of all time.

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.

The day started off shaky for Apple Inc. (AAPL) after its leader and CEO, Steve Jobs, announced that he would be taking his second medical leave of absence yesterday.

The stock was in the red all day, but did rebound a bit at the end of the day, closing today's session down 2.2% to $340.65, after trading as low as $326.00 earlier in the day.

Apple Inc. (AAPL) has had tremendous success with its App store, and it is once again approaching a major milestone as the company's stock continues to soar and set yet another 52-week high today.

Apple stock closed the day at its new 52-week high of $348.48, up 0.8% on the day.

Alaska Pipeline Service, which operates the Trans Alaska Pipeline, on Saturday told BP (BP) and other producers to reduce their output by 95%. An extended shutdown could drive oil prices to $100 per barrel.

This is a nasty situation coming in the middle of winter. The Wall Street Journal quoted BP spokeman Steve Rinehart who said that this is a "significant event." He further added: that the latest shutdown means "a big reduction" in the middle of winter "when we have temperature and weather challenges."

Zynga's unusual twist to gaming has caught the imagination of players around the world and spurred them to play Zynga games. Zynga now has a quarter million users.

Zynga is a worldwide gaming site. Their games offer a different "take." Unlike standard games that move from beginning to finish, Zynga's games require an "energy" characteristic to play. Engaging in "Mission" is a core feature of many games which consumes a certain amount of energy. After expending energy, it slowly replenishes the character's maximum limit. This can take minutes or several hours. In the meantime, players can obtain game credits that allow them to replenish their character's energy or receive premium currency that could be exchanged for other various virtual goods.
