Wal-Mart Stores, Inc (WMT) is the world's largest retailer, competing with companies like Target (TGT), Costco (COST), Amazon (AMZN) and Best Buy (BBY). Our price estimate for Wal-Mart stands at $65.42, which implies a premium to market price.

There are definitely a lot of happy Beatles fans out there today, as Apple Inc. (AAPL) announced that it would finally be selling Beatles material through its iTunes store.

Fans have been waiting, not-so-patiently, for this to happen for years now, and today it has finally arrived. Apple wrote on its website that "In 1964, the band that changed everything came to America. Now they're on iTunes."

Apple's (AAPL) new iTunes-based social networking service, Ping, has gotten off to a somewhat rocky start. The service allows iTunes users to see what others like and to recommend music.

But within 24 hours of Ping's launch it was inundated with comment spam. While Apple filters Ping for other offensive material, it apparently forgot about such spam, an obvious oversight.

Last year, Twitter said it had two goals for 2010: generate revenue and make acquisitions. At the time, the company was still sitting on a significant portion of its last round of capital, and given the $20 million annual burn rate revealed late last year -- plus the revenue it's generating -- it's unlikely that Twitter has had to deplete its coffers. So, Twitter has cash to put to work, and now we're seeing what that means.

On its blog, Twitter announced Friday that it has entered into an agreement with Atebits (aka Loren Brichter) to acquire Tweetie, which is one of the top Twitter clients for the Apple (AAPL) iPhone. In addition to acquiring the application, Twitter is also picking up talent. Brichter's efforts were good for a 2009 Apple Design Award, and he'll be part of future efforts to get Twitter for the iPad off the ground.

Leave it to the lawyers to build a better mousetrap with an iPhone. In the United Kingdom, solicitors Bott & Co found a new question to which the answer is: "There's an app for that." The Car Accident Assistant is the firm's latest contribution to humanity and is available for download from Apple's (AAPL) iTunes environment. If you're in a car accident, you can use the application to connect to the law firm's 24-hour accident help system.

As the ol' infomercial guys love to say, "But, wait! There's more!"

The Car Accident Assistant can be used to help the afflicted collect information about the accident, including vehicles and location. And, you can even take pictures of the accident and gather info from witnesses. It's like having a lawyer in your phone!

Tired of the prudes over at Apple (AAPL), who keep a tight leash on filth in iTunes? Well, it seems like the folks at Google (GOOG) are keeping an open mind. Even though its Android Market isn't playing in the adult space, Google isn't preventing adult-only content from getting on its devices, while Apple has made it a point to keep its iPhones and iPods clean from the start.

The latest entrant into the Android experience is a company called MiKandi (say it, "my candy"), which provides mobile access to the hot stuff you can enjoy on a screen of any size. MiKandi has no connection to Google other than the use of its technology.

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.
