I was trying to access some of the sensors that are built into this Intel Ultrabook that runs Windows 8. However, while there's support for Location Sensors built into the .NET 4 libraries on Windows 7 and up, I want to access the complete Sensor and Location Platform that is built into Windows 8 itself. Those APIs are available via COM and I could call them via COM, but calling them via the WinRT layer is so much nicer. Plus, this is kind of why WinRT exists.
