I'm also considering the weight of keyword domains from the point of .com, .net, .org, etc. It's entirely possible that Google is retaining some value in .com, but lessening the rest.
I too have some exact domain websites that have continued to exist in top rankings. However, I do not think this indicates staying power. It simply indicates that "Google" hasn't deemed that keyword phrase as important enough yet. In other words, one that niche can fit under the umbrella of say, CNET, Engadget etc, that keyword domain will succumb to the new Google way of establishing rankings.
The point I'm making, as I did to start this thread, was to suggest that the value that once was, is actually no longer. The marketplace imo has yet to face that reality. Always counter examples, but I have some experience in this realm.
