Pros

It's a complete solution that has a vast array of pre built components, charts and a data-grid based solution.
Security comes out of the box.
It's mobile and tablet ready.
It has a lot of support from the community so solutions are easily available
You can add your own flavor via theme customizations and built in component extension.

Cons

Being a huge framework with all these components the learning curve is huge as compared to other html5 and javascript frameworks out there today.
It's hard to plugin a custom pure javascript component, you need to stick to components that are part of sdk.
Changing some implementation of a component already defined is not straightforward, it needs a lot of understanding.
It takes a fair amount of time to even get the basic shell of the application up and running if you are starting from scratch.
It's very expensive from a licensing cost point of view.

Return on Investment

Developers are more focussed on implementing the business logic as compared to figuring out technical challenges of some slick user interface component.
Business is happy with the ease of use introduced by the new UI components.
We are well placed to move our application off from a purely web based platform to a mobile and tablet based solution.
