While it originally seemed like that the OS will be filled with so much features and additional content, Microsoft has managed to keep their development cogs turning and churning fast enough to make it to the holiday launch they promised.

At the Mobile World Congress held last February in the beautiful city of Barcelona, Spain; Steve Ballmer took the stage and gave the world its first look at the Windows Phone 7 operating system. Without a doubt, many users of the older Windows Mobile OS were outright impressed with the stylish new user interface, at how smooth all the transitions were and the fact that it made full use of capacitive touch screen controls.

The demonstration ended with a promise that the OS would be delivered to the public by the holidays of this year.

While it seemed that announcing a new almost a full year in advance might have not been a good idea, Microsoft is so far, managing to pull it off. The weeks have been full of new updates, demonstrations, and announcements regarding what will be added and what manufacturers will be making handset for the new OS.

From the basic Zune, Bing and Xbox Live Games features that were shown off at the MWC to the addition of Silverlight, XNA 3D, the new MSN Player and even an upcoming Adobe Flash Player update, there is plenty that this new OS is going to offer t the public. Apple’s iPhone will not only have contend with the open source Android, now it will be matched by another closed system that could potentially be offering even more functionality in the form of the Windows Phone 7 OS.

Business enterprise users have not been forgotten by Microsoft. Despite the general consumer focus of the WP7 OS, they have promised that they will continue the development of the Windows Mobile OS. In fact, they recently launched Windows Embedded Handheld for WinMo.
