If that's the case, why bother using Flash. Why not ust use HTML in a
browser and have all you business logic on the backend? HTML is a
great presentation layer.

Do you use any of the Flash components? What about all the business
logic bulitin to each component? Do you want that on the server? What
about all the business logic associated with getting data in and out
these components? Do them on the server? What about all the business
logic associated with interacting with the user? Do you want that on
the server? What about all the session specific non-saveable data
needed by all this business logic? Do you want transferred to the
server to be processed by the backend business logic?

What is the backend anyway? Isn't it just a web-based database? If it
wasn't for the latency of the internet, this wouldn't be an issue.
We're all building database applications using a client/server model
in which the database is in the server and that server is on the
internet. If the server were on an internal network, you'd use ODBC to
access the data and not bother with using http to access the server.
And in that case, why bother with Flash? What not use Visual Studio or
Cocoa or whatever gui application development tools and libraries
exist for the desktop OS of choice?

Why bother doing that? Why not use Photoshop, Illustrator, Acrobat, a
good colour printer and good quality paper and create paper-based
presentation layer and use PageMaker or FrameMaker put the business
logic into a well designed, well laid out procedures manual for use in
filling in that paper-based presentation layer.
