MS has already showed Office running on ARM. I doubt VFP will run on it.

>Notice I didn't say WinPhone8, I just said 'future Windows Phone'. I lean towards agreeing with you that WinPhone8 is too soon to remove the Silverlight based dev platform. And when a new platform (non-Silverlight is supported), hopefully the Silverlight option will exists for those who want it, and most importantly, for backward compatibility. I worry about the backward compatibility stuff... for example, I read that Windows 8 on ARM may not run all Intel based Windows apps, which could include things like Office or VFP. Then much of the benefits of a Windows based tablet are removed, being able to only run tablet specific apps.
