Jaffa, I have no doubts that new applications will look slick and fit in with our expectations nicely, but for the folks building and devloping existing applications using the standard UI frameworks, will they be compilable and run with minimal modification. It was whether we are going to continue with X but have a compositing manager available so "old style" apps can run. There has been a lot of discussion around from people in this thread and others that they are nervous they will lose the utility of the apps they have now and my question was an attmept to clarify that.
Also, without the SDK we are restricted from what we develop - is it worth continuing to build applications using the frameworks as they stand now, or do people enter a a holding waiting for the SDK (as you are..)
On a side note, Jaffa you mentioned last night that I was building emacs or my own OS
