AIR applications have started appearing and they are coming up fast. Last week I spotted a IM Messenger built using AIR and is pretty good! Here is a list of AIR applications that I found few minutes ago. Its built in wiki and anybody can add a new application to the list. At present the list is about 78 and I am sure this will grow.
For all the Adobe AIR enthusiast, this list will give you a good collection of AIR applications!
