Given their history with Apple, it's pretty surprising that Microsoft, the biggest software company in the world, has not released a competitor to the iPhone since it first hit markets 3 years ago. That changed earlier today with the announcement of Windows Phone 7 Series, their response to Apple's iPhone and Google's Android OS. The new OS has a lot of cool things that set it apart from the iPhone. The name doesn't seem to be one of them, but the features may make up for it for many people.
