Many expected and thought that Windows Phone 7 would be based upon the Windows CE 6 kernel. According to Oliver Block, the platform will actually be based upon Windows Embedded Compact 7 core. Microsoft’s official statement claims Windows Phone 7 is built using the latest release of CE6 (version R3). Apparently, they “incorporated innovative features and functionality on top of the platform.” Their official statement follows:
Windows Phone 7 is based on the Windows Embedded CE kernel – the next generation of the Windows Embedded CE platform will be Windows Embedded Compact 7 when released, and the current version is Windows Embedded CE 6.0 R3. Although Windows Phone 7 was built on the Windows Embedded CE kernel at its core, the Windows Phone team has incorporated innovative features and functionality on top of the platform to develop an OS specifically designed to meet the needs of mobile phone manufacturers.
What’s this all mean? Sounds as if they are transitioning to a yet unfinished Compact 7 Kernel, thus requiring them to use a hybrid. In any event, let’s just hope things are progressing for that holiday release.
