That forthcoming Microsoft’s Windows Phone 7 Series is a clean break from the past – sans either any muddled legacy of Windows Mobile or a backward compatibility with Windows Mobile - is evident from the fact that the product not only looks and feels different from its predecessors, but also boasts a newer way for software makers to write programs.

While the details forwarded about the Phone 7 Series at the Mobile World Congress showed that the new operating system is closest in appearance to the Zune HD, rather than to any other older version of Windows Mobile; Microsoft Thursday confirmed that the key tools for developers will be Silverlight and XNA.

With the Windows Phone 7 Series clearly using a ‘radically different’ approach to organizing information and apps, reports indicate that the reports, the most compelling feature of the Windows Phone 7 is the concept of ‘decks’ that assemble different information streams – allowing users to organize the streams according to their respective area of interest.

Microsoft is promoting the Windows Phone 7 platform largely as a consumer device – focusing chiefly on its Xbox Live-style gaming, social media usage, and Zune music and video playback. However, accompanied by a version of Microsoft Office, the seemingly ground-breaking Windows Phone 7 would also include the enterprise security and manageability that businesses have long relied on.
