We've been looking forward to this for a while, and now it's here: Adobe AIR runtime for Android. That means developers using Flash Builder or Flash Professional CS5 can publish AIR apps directly to the Android Market, and all users will need is this little runtime from the Market and they're set. AIR's desktop-oriented .air packages aren't compatible, so you can't just go and grab anything, but there are AIR apps already starting to pop up -- AppBrain has a whole list of them in one of the source links below -- since Adobe has been trialling this with developers for a little while now.
