I think about it when I started to use Kendo UI. I try it in a large application web for compay management and I think that the result is so powerful , robust and pretty.
The only that I needed is a JS framework for the scroll of a kendo window. Maybe the requirements of my work was simple, but the Kendo UI it's cover all my necesities.
I think that you can do it all with Kendo UI with imagination... I did it, with my experience. All depends of your application requirements ;)
