Finally! Adobe AIR is now available on Linux, though it is not a full-featured release yet. The good thing is that this release includes the SDK and Flex Builder 3 along with the runtime. Adobe had left Linux out of their 1.0 release, but now seems to be abiding by its promise. In fact, Adobe has joined the Linux Foundation in a bid to speed up development on Linux. I think technologies like AIR are important, they will offer the balance against taking everything to the browser. And being cross-platform is a key attribute to make this happen.
