Let's say IBM touted a native GUI offerring tomorrow, how much would you be
prepared to pay for that?
How much is your boss gonna be prepared to pay for that?
When he goes to the business and they ask what is that going to give us that
we don't have already with green screen or browser, what's the response?
IMHO, the browser of today can do everything a native GUI could do and
more...we just need to make more use of the amazing tools we have already
been given!

Generally speaking, it may take 5-20 times longer to write HTML, CSS, and
JavaScript than display file DDS, depending on one's skill level.
But regarding application development in general, wouldn't one's
productivity depend on whether the application fit a model or design pattern
that they've already built before, or whether completely new code must be
written?
Personally, I specialize in Web applications that follow pre-defined models,
so my productivity in that respect is better now than it ever was at
green-screen development.
Or allowing both, depending on what type the user prefers?
Personally, I don't think I would have gone to the trouble of developing
models for Web applications if I didn't think I could come up with one that
was more productive and offerred more features than the traditional IBM i
"work with" model. Users prefer mine.
But your question raises a good point about modularizing code, following MVC
design techniques, so you could do both. And my models separate DB I/O and
business rules into modules that could interface with both browser and
green-screen clients.

You should meet the new IBM. They have been quietly, but systematically
buying application development firms and building their custom technology
group, and moving much of their development operations overseas.
That's not to say that IBM doesn't vasillate back and forth, appeasing
business partners when they see fit, but their tendency is to move steadily
into space that business partners previously occupied.
I have no doubt that if Rochester were to convert IBM i to a native GUI, the
platform would take off. But at what cost? Who would license RDI-SOA? Who
would need Websphere and all the configuration and performance management
services that accompany it?
