I've been contacted by a couple of potential customers about how the AIR story compete with Silverlight. This has also come up at several talk i've done recently. I am not an Adobe or Flash guy so I may be the wrong one to broach the subject, but it feels like they are not necessary competing. In a large way it feels like Microsoft is trying to get into the web space and compete for RIA, whereas AIR seems to be attempting to get onto the desktop.
