Adobe Air Apps

So far this year I have been very impressed by some of the Abobe Air applications. Specifically twhirl (http://www.twhirl.org/), the recently released Alert Thingy (http://alertthingy.com/), and Tumbleweed (http://tumblweed.org/) of which I am currently using to write this post. Not only are all AIR apps cross platform so I can use on both my Mac and PC, but they all offer some additional functionality over their respective websites. If the filtering is done appropriately, ultimately Alert Thingy may replace Twhirl on my desktop. In addition to multimedia, I imagine there could also be some VOIP scenarios here..
