Adobe is about to release AIR 1.0, which means that AIR will cross a huge milestone. AIR is a cross platform merge the desktop and the Web, and develop rich applications. I think this is a milestone not only for Adobe, but for the technologies which can offer webified applications.
However, it is still a wannabe as it is not available on the Linux platform yet. Not that Adobe is not taking the effort, the pre-beta testers are being called for, and Adobe is bringing other tools to Linux as well. But I wonder if it could have been better than a 1.0-without-support-for-Linux, especially because both – users and developers are shifting to Linux.
