The Adobe® AIR, runtime enables you to have your favorite web applications with you all the time. Since applications built for Adobe AIR run on your desktop computer without a web browser, they provide all the convenience of a desktop application.
Companies like eBay and AOL are using Adobe AIR to create exciting new applications that allow you to use their services on your desktop.
In short, Adobe AIR means applications that are easier, more powerful, and more fun to use.
Be safe on the web: Adobe AIR helps ensure safe installations by requiring digital signatures on each AIR application that identify the application and its creator before you install.
