Microsoft's Looking To Reboot Mobile with New Software and Hardware: Sources

Long time Microsoft watcher Brad Sams, reporting today: Two independent sources inside of Microsoft have told me that there is a new hardware device being tested internally and that there is also a separate branch of Windows Mobile for this device. I have been hearing about the software update for some time and the added hardware component makes sense as the company is pursuing "new experiences" with this device. Additionally, the UI is expected to be different than what we know today as Windows Mobile but the exact changes are still evolving as we are in the early days of development of this experience. There may also be another 'cut' in the support for older applications with the new mobile experience. I have heard, but am not able to fully confirm at this time, that Silverlight applications may not longer work with the updated OS.
