Linux users, say goodbye to Air. Adobe has announced that version 2.7 will be your last official release and, going forward, you'll have to rely on kind-hearted souls willing to fire up the Linux porting kit the company will be providing. Development teams will instead be focusing on the growing realm of mobile and improving Air support on iOS and Android, and likely bringing the browser-plus-flash app environment to webOS. With the world's favorite open-source operating system holding steady at roughly one-percent of the desktop market it's hard to take issue with the choice. Of course, it probably doesn't help that Adobe has had trouble getting it to play nice with *nix -- especially the 64-bit flavors. Besides, with Tweetdeck prepping a proper web-app, what do you need Air for anyway?
