OK fair enough but do you think C# based is the way to go?
No, deploying new applications under Windows will come back to bite
eventually. It adds unnecessary cost and complexity. I would steer them
away from that. Much better to host both applications and data on IBM i.
Actually I have been working with mobile apps lately connecting a desktop
system using Delphi...
Sorry, the thought of using Delphi in connection with "mobile apps" sounds
rather incoherent; what does Delphi have to do with mobile apps?
I think it hard but what are their choices?
That's a really open-ended question; The options are seemingly limitless.
As a replacement for green-screens, I would suggest a discussion about
"single page applications" and "responsive design", which was discussed at
length on the Web400 list last month. Following is an example which is
hosted on our IBM i server:

Responsive design is about creating user interfaces that look and work well
on cell phones, tablets, laptops, and desktop screens. I would suggest
testing that link, using multiple devices.
Single page applications may appear have multiple screens (ie. list and
detail), but all views are actually contained in just one HTML page, which
leads to a more fluid and better performing user interface.
Single page applications are generally supported by JavaScript and CSS
frameworks, which reduce the amount of client-side code required. In the
sample application cited above the client-side code is reduced to a few
JavaScript functions which respond to key events.

The word "magic" is sometimes associated with SPA frameworks; if you
right-click on the screen to view "source", you won't see much of anything.
The framework is doing most of the work behind the scenes; very little
coding required.
