Like myself, I am sure there are alot of individuals out there looking to get an explanation of what is all the hype with Adobe Air. You can visit Abobe Labs to find out more on Adobe AIR, but I did come across an article by Blue Clock which breaks down many questions you might have about Adobe AIR. Some of the questions answered put into perspective are

• What exactly is Adobe Air?
• Is it a Web or a Desktop Application?
• Why does Adobe Air Matter?
• Who is using Abobe Air?

This article is a nice start and resource to understanding Adobe Air. Also, I would recommend visiting these sites for more info on Adobe AIR:
