That's an interesting point:  I would say targeting HTML(5) can be
successful without guaranteeing same results across browsers.  It might be a
formidable amount of work to try to guarantee results given that the browser
manufacturers themselves don't care and have successfully pushed that task
on the developers.

Yes, things get faster, but I would say that performance has been an issue
for Flex for its entire lifetime, and faster devices have not alleviated the
problem.  If Flex 1.0 had gone for a cleaner architecture, it isn't clear it
would have been successful enough to end up here in Apache.
