I have a basic question. Do you feel that the kinks (if any every existed) are worked out between Ext and Air. I want to recommend an Ext+Air vs a Java Swing app as the UI layer. However this is a mission critical app for my client and I want to make sure I won't regret my decisions. In other words once you get pass the cool task demo can Ext+Air deliver a top notch product?
Also are there any pitfalls or show stopper that you have come across using Ext+Air?
Thanks for any input
