I think that the RT ideal is great...as an ideal. I think that experience shows that being able to reuse components (in some form - that is a interesting and in depth technical discussion right there) is key.

Looking forward, I think that the "Metro" UI doesn't sit well in the enterprise. Perhaps there are aspects of it that could be viable but it doesn't sit well with data entry apps, office apps and most administrative apps like timesheet apps. I have yet to see an example of a UI that uses the Win 8 app UI that would bring any of this to the desktop of the average office working (I am not even considering IT roles either).

I too cannot see the next buzz in data (except a continuation or refinement of those from 2013).

HNY!!!
