During the annual Japanese Microsoft Developers Forum, the public was able to get its first glimpse at the new Windows Phone 7.5 OS, which has been in development for quite some time. Microsoft CEO Steve Ballmer believes that the ‘Mango’ OS will help the company to reassert its dominance in the mobile market. The Windows Phone 7 was met with both harsh criticisms as well as a lukewarm reception by devoted Microsoft fans. As an innovator in the technology sector, Microsoft is expected to deliver innovative designs with every new product line that is introduced.

In the smart phone world, iPhone may be king for now, but Microsoft has a really good chance of taking over with the new planned updates. Ballmer promises more than 500 new features on the ‘Mango’ OS. He didn’t go into a lot of details about specifics, but he did promise that the new OS would change the way that smart phone users communicate in the future.

Microsoft is planning a huge global launch in which Window Phone 7 owners will have the ability to be amongst the first to try out the new OS. There have been rumors surrounding the recent acquisition of Skype, as well as the direction that Microsoft plans on taking the company into. It is possible that the new ‘Mango’ OS will make use of Skype’s video chat based platform, but only time will tell what Microsoft has managed to come up with. No official release date has been set, but the ‘Mango’ OS will likely be available by the end of the summer.
