Mike - I know very little about this but here is how I understand it.....
(some big guesses in here so correct me if I'm wrong)

FLEX lets you dynamically generate flash movies, *kind* of like generator
did. At the moment you can pump dynamic data up to these movies via text
files, xml streams or flash remoting. This data is them processed client
side by the flash player & the code you have written and is rendered as
flash content.

What flex adds to this mix is the ability to generate Flash content
server-side and pump it up into the client. I can see a bunch of benefits
of this sort of thing, including in client side performance.

Another advantage is that there is now a standard way to mark up flash
content (MXML) in the same way we currently mark up normal web content. So
if I'm a WYSIWYG type person I can use flash to make my interface, however
if I am a code type person I can use homesite or notepad or anything else I
like.

This also opens up a heap of possibilities on the scripting & content
management side - For example, I have a CMS that generates XML content I can
Content -> XSLT -> HTML -> Browser or I can Content -> XSLT -> MXML -> Flash
Player or I can Content -> XSLT -> RSS -> News Reader, etc... Central
content management and multiple delivery formats.

CSS for style, XML for content & ECMAScript for interactivity are becoming
increasingly standard - I'm very happy to see Flash move in this direction.

AFAIK HALO is a set of "skins" that MM released for flash developers to work
with - lots of generic skins for common interface elements.

So the big deal is not that you can deliver better end product to your
users, but that there are better, more powerful and more flexible  ways go
through the delivery process. Is it more complicated? Well its something new
to learn, but that's IT for you...


Cheers

Mark
