Arguments why using vaadin / Number of projects realized by vaadin

Hi there,

we are a IT solutions software company. We are evaluating different kind of web application frameworks.

I would like to choose vaadin.

Does anybody know, exists there a number, in how many professional projects vaadin is used?

Does some documents exist, which could help me to argument, why we should choose vaadin.

Regards
Uwe
