Dell  announced a “getting rid of BlackBerry” program starting next week. The company’s reasons are straight admitted by Brain Gladden, the computer marker chief financial officer “Clearly in this decision we are competing with RIM, because we’re kicking them out”.

By switching BlackBerry to Windows Phone 7, Dell will cut costs of almost 25% of the total communication spending. In addition to the public replacement of BlackBerry phones among the Dell’s employees, the computer manufacturer also contacted T-Mobile USA, requesting voice minutes and data packages to cover the necessity of the company in terms of communications.

The competition between BlackBerry manufacturer – RIM and Dell is obvious, as the former one gained market share and impressive revenues by developing on the smartphone market. To diminish the gap between the two giants, Dell also expressed their interest in selling online on eBay the used Blackberry phones and moreover, they sustain the idea that their debut will encourage other companies to replace BlackBerry with Windows Phone 7.

In response to Dell’s allusively announcements, RIM replied that what is Dell doing is nothing but self publicity on BlackBerry’s image and more, the expected outcomes will not be achieved because of the high cost implied in the implementation of a new technology – servers and software for Windows Phone 7 “We find it highly unlikely that they will actually save any money with this move and far more likely they were looking for a little free publicity.”

Dell is granting more consideration to the emerging devices developed around Windows and Apple because they settle the future way: concern for software solutions than devices – whose prices are getting lower.  If Dell speculates the move as a marketing tool, Apple and Windows are pushing the app industry forward. The same strategy applied Microsoft with its Windows Phone 7.

But Dell’s not the only one moving away from BlackBerry smartphones.  Bank of America and Citigroup, two financial industry companies, are looking to the iPhone to replace their employees BlackBerries.  It’s an enterprise shift effecting a number of companies, within finance and beyond, hoping to make their workers more effecient.  Of course, there are often incentives for providing such a large employee base with one type of phone over another, and we’re seeing some hefty marketing investments from Apple and Microsoft on the business end.

In the end, this trend is certainly an opportunity for all mobile platforms involved, especially as Microsoft hopes to regain widespread relevance for the consumer market, following a similar path as it did with Windows in the 1990s.
