Adobe's launching AIR, its cross-platform runtime, for smartphones. Why's that a big deal? It theoretically means developers can write an app once, and it'll work on tons of OSes—at least any that support AIR. Oh, and the iPhone.
Android's the first to get AIR, but WebOS, BlackBerrry and Windows Mobile are slated to get it too. And remember Adobe's initiative to push Flash apps onto the App Store for the iPhone? Apps developed for that will work just fine in AIR on other phones, letting Adobe have their iPhone cake and eat it too.
