It still is. In fact AIR might be the simplest choice out there, since you can develop for it with web based technologies. But it is severely restricted when it comes to accessing native desktop APIs. The default look and feel are very ...web-ish, that might or might not be what you want. One thing for sure is that the look is pretty consistent as they include a Webkit rendering engine. My biggest gripe with with AIR is that the user has to install Adobe AIR before he can install your application and you know how Adobe installations are.
