I have (quite rightly) stayed out of this conversation since I am not in a
position to comment on the technical discussion (although I do tend to agree
with Mark as I follow the thread).

I would, however, like to comment on the assertion that Bjoern makes that
"...Users want web applications to respond to their actions before they have
been fully loaded..."  While you have the right to your opinion, can you
actually back this statement up with factual data that *proves* this
statement?  As I am primarily an accessibility advocate, I would venture to
guess that users of Adaptive Technology such as Screen Readers may disagree
with you; the way that they interact with web pages/application relies, in a
large part, with them being able to access all data in a linear fashion, and
not in a "whole page scan" model that most visual users would adopt.  For
this reason, developers should actually avoid triggering user-actived
scripts part way through the load process
(http://juicystudio.com/article/making-ajax-work-with-screen-readers.php).

Just another wrinkle in the discussion.
