The deal underscores Apple's push to expand the reach of the iPhone and iPad into the business world beyond their traditional base among consumers. IBM meanwhile, is hoping Apple's simplicity and popularity will help stem eight consecutive quarters of year-over-year revenue declines, as it moves more of its business software onto the mobile devices used by employees.
No, I do not believe that IBM's choice to sell apple products will result in a mobile monopoly. There are an enormous amount of Android products in the market, and the success that has been seen in these products should serve as evidence for the low possibility of the development of a mobile monopoly.
There are many competitors in the mobile industry. Samsung, HTC and many other companies hold large shares of the market. One of apples big selling points to their loyal followers is that they are "different" and not IBM or a compatible product. This move may actually backfire and have a negative appeal to long time apple loyalists.
First and foremost, Apple may have a big percentage of the mobile market, but not all. There are plenty of other mobile product producers. A monopoly is defined as: "the exclusive possession or control of the supply or trade in a commodity or service." Sure, IBM will have a large chunk, but not an exclusive chunk.
