> Windows Phone OS isn't really a profitable business for Microsoft<p>Microsoft has always had decade long plans for certain products. For an example just look at XBox.<p>I would say Windows Phone is just such another long term project and it is just starting it's next stage with their purchase of Nokia's phone division.<p>> but they can make users stick with Microsoft products.<p>The mobile space is one of the most fluid of any business.<p>For that space I don't think any company has much control over their user base.<p>Samsung has shown this only to well with their ability to woo iPhone users away from Apple. Who would have thought a company like Apple, with some of the most loyal users, would find themselves loosing out so badly to the upstart Samsung.<p>> Look how Google has been getting advantage from Android users who are using default Google applications installed on Android devices.<p>Google gets most of it's income from advertising, Microsoft from selling software. Unlike Microsoft, Google can give away free software and it does not effect it's bottom line.
