The site/message is good, but I'm not sure I would ever promote any in-flight entertainment system as a great example of a development framework in action. Almost every one I've used has been among the slowest, clunkiest, crashiest, most unresponsive, poorly designed "modern" UIs I've ever used.

In order to avoid being entirely critical, however, Qt does serve a role that few other dev platforms do, and although I suspect there are better alternatives, I'm glad that there is still strong support for it!
